Buffer Overflow
Monthly
Out-of-bounds table access in the Linux kernel fp9931 regulator driver exposes kernel memory to corruption via a malformed VPOS/VNEG voltage selector lookup table. The fp9931 driver's VPOSNEG_table[] contains two defects: a duplicate 7.04V entry that shifts all subsequent selector mappings by one, and a truncated table of only 41 entries instead of the required 64, meaning any selector value above 0x28 triggers an out-of-bounds access in kernel memory. Devices incorporating the FP9931 PMIC (a display-panel power regulator) running affected kernel versions are vulnerable; exploitation probability is very low (EPSS 0.20%, 10th percentile) with no public exploit and no confirmed active exploitation.
Out-of-bounds kernel memory read in the Linux kernel DRM log subsystem allows a local low-privileged user to potentially disclose kernel memory contents or crash the system. The flaw resides in drm_log_draw_kmsg_record(), where an unsigned integer underflow on a zero-length message causes an array access at offset UINT_MAX (0xFFFFFFFF) rather than a valid buffer position. No public exploit exists and EPSS sits at 0.20% (10th percentile), indicating low observed exploitation interest, though the kernel DRM panic-display path is reachable on any system with a GPU using the DRM framework.
Out-of-bounds write in the Linux kernel's `dev_validate_header()` network function allows a local process holding `CAP_SYS_RAWIO` to corrupt kernel memory by sending a raw packet with a short link-layer header while the target network device is concurrently reconfigured to increase `hard_header_len`. The `memset` zero-padding operation writes past the skb headroom reserved at allocation time, producing a silent memory corruption that is worse than the pre-existing `skb_under_panic()` it masks. Patches are available across multiple stable kernel branches; EPSS stands at 0.24% with no public exploit or CISA KEV listing.
Stack buffer overflow (CWE-121) in the file-level restore agent of Dell PowerProtect Data Manager versions 20.2.0.0 and below enables attackers to potentially achieve full system compromise, including code execution. The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, score 7.8) indicates local access with low privileges, while the vendor description separately references a 'high privileged remote attacker' - a direct conflict in both attack vector and privilege level requiring vendor clarification. No public exploit or CISA KEV listing exists at time of analysis.
Buffer overflow in TOTOLINK CP450 4.1.0's web CGI handler allows low-privileged remote attackers to corrupt memory and likely execute arbitrary code by supplying an oversized value to the `topicurl` argument in `/cgi-bin/cstecgi.cgi`. The CVSS 4.0 threat metric E:P confirms proof-of-concept exploit code exists, elevating this beyond a theoretical concern. No vendor patch or advisory has been published, leaving affected devices exposed with only compensating controls available.
Heap buffer overflow in zlib 1.3.1.2 through 1.3.2 allows remote attackers to corrupt memory via crafted input to applications using the non-blocking gzwrite API. The gz_vacate() function fails to bounds-check a memmove() when stale external buffer pointers are present after a write stall, reachable by calling gzprintf() or gzvprintf() in that state. A publicly available proof-of-concept exploit exists; no vendor-released patch has been identified at time of analysis.
Verifier bypass in PREVAIL, the polynomial-runtime eBPF verifier (used notably as the abstract-interpretation verifier in ebpf-for-windows), affects all versions prior to 0.2.4. When a destination register carries a non-singleton typeset - two or more simultaneously possible pointer types, e.g. {ctx, shared} or a {number, pointer} union - EbpfTransformer::add() silently skips updating the pointer offset variable, leaving a stale pre-add offset. Subsequent bounds checks reason from that stale offset and accept out-of-bounds memory accesses, so a crafted BPF program that would corrupt memory at runtime is incorrectly accepted as safe; the fix landed in 0.2.4 and no public exploit has been identified.
Heap out-of-bounds write in NGINX JavaScript (njs) xml.exclusiveC14n() allows unauthenticated remote attackers to crash NGINX worker processes or cause unbounded memory growth, with theoretical code execution that has not been demonstrated. The vulnerability is directly reachable in the nginxinc/nginx-saml reference SAML SP implementation, which passes untrusted InclusiveNamespaces/@PrefixList values to xml.exclusiveC14n() before signature verification completes - meaning no valid SAML signature is required to trigger it. Both the njs (default) and QuickJS engines are affected, with differing crash-vs-leak behavior, but both result in denial of service. No public exploit is identified at time of analysis.
Heap buffer overflow in PX4 Autopilot's sd_bench command allows adjacent unauthenticated attackers to crash the flight controller or potentially execute arbitrary code by supplying a block size parameter smaller than four bytes. The overflow occurs because a fixed four-byte block number is written into a heap allocation sized by the user-supplied block_size value - when that value is 1, 2, or 3 bytes, the write extends beyond the allocated region. No active exploitation has been confirmed (not in CISA KEV) and no EPSS score is available, but the adjacent network attack vector means exploitation is constrained to operators with direct access to the drone's MAVLink control network.
Stack-based buffer overflow in the GPU component of Google Chrome on Windows (prior to 152.0.7977.75) enables full sandbox escape and arbitrary code execution on the host operating system. Exploitation is a two-stage chained attack: an attacker must first compromise the renderer process (via a separate vulnerability or exploit), then leverage this GPU flaw to break out of Chrome's sandbox and execute code with elevated host privileges. Google has released a patch in the stable channel update for desktop; no public exploit code or CISA KEV listing has been identified at time of analysis.
Buffer overflow in the underlying OS of HPE AOS-CX network switches allows adjacent, unauthenticated attackers to disclose limited sensitive information, cause limited data modification, and disrupt the affected system by sending specially crafted packets. The CVSS 7.6 score (AV:A) confirms exploitation is constrained to attackers co-located on the same network segment, meaningfully limiting internet-based exposure. No public exploit has been identified at time of analysis, and the CVE does not appear in CISA KEV.
Silent stack-based buffer overflow in Pyramid Solutions' NetStaX EtherNet/IP Stack before v5.6.1 lets a remote attacker send an oversized Class 3 explicit-message request that overruns the application-side receive buffer without any CIP error being returned, causing memory corruption, device crash, or a potential remote code-execution path. Any industrial device embedding the affected stack for EtherNet/IP communication is exposed over the network with no authentication. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Heap-based buffer overflow in the gvfs SFTP backend (gvfsd-sftp) exposes GNOME desktop users to process-level denial of service or potential arbitrary code execution when connecting to a malicious SFTP server. The read_reply() function trusts the server-supplied response length without validating it against the client's allocated buffer, allowing a rogue server to overflow adjacent heap memory in the gvfsd-sftp daemon. No public exploit or CISA KEV listing is confirmed at time of analysis, but the high CVSS score of 8.8 and the C:H/I:H/A:H triad reflect worst-case RCE potential once a user mounts an attacker-controlled share.
Unauthenticated denial-of-service in Rockwell Automation RSLinx Classic allows a remote attacker to crash the communications service by sending a crafted CIP packet containing an oversized embedded message request. The buffer overflow (CWE-120) causes the RSLinx Classic service to terminate, requiring manual restart to restore industrial device connectivity. In OT/ICS environments where RSLinx Classic bridges engineering workstations to Allen-Bradley PLCs and HMIs, service loss can halt production operations or degrade visibility into live industrial processes. No public exploit or CISA KEV listing confirmed at time of analysis.
Unauthenticated remote denial-of-service in Rockwell Automation CompactLogix 5380 and ControlLogix 5580 industrial controllers allows a network-adjacent attacker to trigger a Major Nonrecoverable Fault (MNRF) by sending a malformed CIP message with an invalid input length, requiring a physical power cycle to restore controller operation. The vulnerability is rooted in CWE-119 (improper buffer bounds restriction) during CIP message processing on EtherNet/IP-accessible PLCs. No public exploit code or active exploitation has been identified at the time of this analysis, but the zero-prerequisite network attack surface on safety-critical industrial hardware makes this a prioritized remediation target for OT security teams.
Memory safety vulnerabilities across multiple internally discovered bugs in Firefox 154 and Firefox ESR 153.1 allow network-based attackers to potentially achieve full browser compromise through memory corruption (CWE-119). Mozilla's own advisory clusters dozens of individual Bugzilla reports - including buffer overflows and related defects - under a single advisory umbrella, noting that sufficiently motivated attackers could likely exploit some of these bugs. Vendor-released patch is available: Firefox 155 and Firefox ESR 153.2. No public exploit identified at time of analysis.
Memory corruption in Mozilla Firefox 154, Firefox ESR 153.1, and Firefox ESR 140.14 stems from a batch of internally discovered memory-safety defects that Mozilla presumes could be exploited to run arbitrary code within the browser process. The flaws were found by Mozilla's own developers and fuzzing efforts (no external report), affect the mainline and both ESR trains, and are resolved in Firefox 155, ESR 140.15, and ESR 153.2. There is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.17%, 6th percentile).
Memory-corruption defects in Mozilla Firefox 154 were discovered internally by Mozilla and bundled under CVE-2026-84142 (advisories MFSA2026-82 and MFSA2026-86), and fixed in Firefox 155. Several of the reported Bugzilla issues showed evidence of memory corruption that Mozilla presumes could have been exploited with sufficient effort to achieve code execution when a user renders malicious web content. There is no public exploit identified at time of analysis and EPSS is low (0.14%), consistent with an internally-found, pre-disclosure fix rather than active abuse.
Memory corruption in the Graphics: ImageLib component of Mozilla Firefox stems from an integer overflow when handling image data, potentially allowing remote attackers to corrupt heap memory and achieve code execution when a victim renders malicious image content. Mozilla fixed the issue in Firefox 155 and Firefox ESR 153.2 (advisories mfsa2026-82/85/86/88). It carries a critical 9.8 CVSS score, but EPSS is only 0.14% (4th percentile), it is not in CISA KEV, and no public exploit was identified at time of analysis.
Memory corruption vulnerabilities internally discovered across multiple Firefox release lines (154, ESR 153.1, ESR 140.14, ESR 115.39) could enable remote code execution when a user visits a specially crafted webpage. Mozilla's security team identified a cluster of memory safety bugs spanning 15+ tracked Bugzilla issues, several of which showed direct evidence of memory corruption sufficient to presume exploitability with sufficient attacker effort. Patches are available across all affected branches (Firefox 155, ESR 115.40, ESR 140.15, ESR 153.2); no public exploit code or CISA KEV listing is associated with this advisory.
Remote code execution in the Tenda A18 Wi-Fi router (firmware v15.13.07.09) arises from an unauthenticated buffer overflow in the fromSetCmdlineRun function, letting a remote attacker corrupt memory and run arbitrary code on the device. The CVSS 9.8 vector indicates network-reachable, no-authentication, no-interaction exploitation, and a public repository (github.com/momo8877847/Tenda-A18) appears to document the flaw, so publicly available exploit code likely exists. There is no CISA KEV listing and EPSS is low (0.30%), indicating no confirmed widespread active exploitation at this time.
Memory corruption via classic buffer overflow in WebKitGTK allows remote attackers to achieve full code execution by delivering malicious web content to a victim user. Affecting Red Hat Enterprise Linux versions 6 through 9, the vulnerability requires no authentication and no special configuration - only that a user process attacker-controlled web content through a WebKitGTK-based application. No public exploit has been identified at time of analysis, but the CVSS 8.8 High rating and full CIA triad impact make this a high-priority patching target across the affected RHEL fleet.
Integer overflow in MSI Dragon Center's NTIOLib_X64.sys kernel-mode driver (versions up to 2.0.155.0) allows local low-privileged users to corrupt kernel memory via crafted count or elementSize arguments passed to the MmioWritePath MMIO Write Path Handler. Exploitation can yield full SYSTEM-level privilege escalation on the target host. A public proof-of-concept is available, the vendor did not respond to coordinated disclosure, and no official patch has been released.
Out-of-bounds heap write in GDB's legacy STABS debug format parser allows arbitrary code execution within the GDB process when a user opens a crafted ELF binary. The root cause is a linked-list removal bug in `read_member_functions()` (gdb/stabsread.c) that retains destructor entries in the main function list after decrementing the length counter, causing the subsequent array copy to write beyond allocated bounds. Confirmed under controlled conditions to achieve command execution within GDB; no inferior process execution is required, and no public exploit code is known at time of analysis.
Out-of-bounds write in D-Link DSM-G600 firmware 1.01 exposes the device to remote memory corruption via a malformed multipart request to the /load_file.cgi endpoint. A low-privileged, network-adjacent or internet-accessible attacker can trigger CWE-787 in the Multipart Handler, potentially achieving arbitrary code execution with full confidentiality, integrity, and availability impact on the device. A public proof-of-concept exploit has been disclosed; no vendor patch has been identified, consistent with D-Link's typical end-of-life posture for legacy NAS hardware.
Stack-based buffer overflow in TOTOLINK NR1800X firmware 9.1.0u.6681_B20230703 enables remote code execution through the device's web management CGI interface. The setUploadSetting handler fails to validate the length of the FileName parameter before copying it onto the stack, allowing an attacker with low-privilege access to overwrite control data and execute arbitrary code on the router. A public proof-of-concept has been disclosed on GitHub, materially increasing exploitation risk even in the absence of a confirmed vendor patch.
Stack-based buffer overflow in D-Link DIR-825M firmware 1.1.8 enables remote code execution via the web management interface's disk formatting endpoint. The `partition` argument to the `sub_46725C` function at `/boafrm/formDiskFormat` is not bounds-checked (CWE-119), allowing a low-privileged authenticated attacker to overwrite the stack and achieve arbitrary code execution on the router. A public proof-of-concept exploit exists, substantially elevating practical risk; no CISA KEV listing has been confirmed at time of analysis.
Stack-based buffer overflow in the D-Link DIR-825M 1.1.8 LTE Module Firmware Upgrade handler allows low-privileged remote attackers to achieve remote code execution by supplying an oversized fota_url argument to /boafrm/formLtefotaUpgradeFibocom. The CVSS 4.0 vector scores this at 8.6 with subsequent-system impact (SC:H/SI:H/SA:H), reflecting the potential to compromise the attached Fibocom LTE module as well as the primary router. A public proof-of-concept exploit is available on GitHub, significantly lowering the bar for exploitation; no public patch has been identified at time of analysis.
Out-of-bounds write in Exiv2's RemoteIo::Impl::populateBlocks() affects all versions prior to 0.28.9, exploitable only when Exiv2 is invoked with a remote URL as input rather than a local file path. Memory corruption from the write could theoretically enable code execution in the Exiv2 process context if a user or automated pipeline fetches a specially crafted image from an attacker-controlled server. Fixed in the 0.28.9 release; no public exploit or KEV listing identified at time of analysis.
Out-of-bounds read in Exiv2's CrwMap::decodeBasic() function affects versions prior to 0.28.9, impacting applications that use the library to parse Canon CRW image metadata. Classified as low severity by the Exiv2 maintainers, this flaw has only been reproduced using a dedicated fuzz target - the standard exiv2 command-line tool cannot trigger it under normal operation. No public exploit exists and no active exploitation has been identified, making real-world impact minimal despite the memory safety class of defect.
Remote code execution and device takeover in the Tenda HG10 (firmware build 300001138) is possible through a stack buffer overflow in the Boa web server's formIPv6Routing handler, reachable at /boaform/admin/formIPv6Routing. An oversized destNet parameter overflows a fixed-size buffer (CWE-120), letting a remote attacker crash the device or execute arbitrary code with the web server's privileges. Publicly available exploit code exists (VulDB), though the issue is not listed in CISA KEV and no active exploitation is confirmed; EPSS is not provided.
Memory corruption in TOTOLINK A720R router firmware 4.1.5cu.630_B20250509 allows authenticated remote attackers to trigger a buffer overflow in the MAC filtering subsystem, with potential for arbitrary code execution. The vulnerable path is the `setMacFilterRules` function within `cstecgi.cgi`, exploitable by sending a crafted `desc` argument over the network. A public proof-of-concept is available on GitHub; no CISA KEV listing exists at time of analysis, but the combination of network reachability and published exploit code meaningfully elevates real-world risk.
Out-of-bounds kernel heap write in the Linux kernel's GRO (Generic Receive Offload) BIG TCP path allows corruption of memory before skb->head when aggregating oversized (>64KB) packets. The flaw stems from skb_gro_receive() using a loose headroom check introduced by the IPv4 BIG TCP support commit (b1a78b9b9886); crafted frames - for example injected via AF_PACKET with a MAC header under 8 bytes - pass validation, so ipv6_gro_complete()'s memmove() for the temporary HBH jumbo header writes before skb->head and wraps skb->mac_header. It also let software VLAN and encapsulated flows (SIT/IPv6-in-IPv4) aggregate beyond 64KB. No public exploit is identified at time of analysis and EPSS is low (0.19%), and the issue affects only older stable branches (e.g. 6.18.y), not mainline 7.0+.
Integer overflow in Klever-Go's semi-fungible token (SFT) add-quantity path prior to version 1.7.19 allows a mint-role holder to bypass a finite per-nonce MaxSupply constraint, minting approximately 9.2×10^18 tokens in a single transaction. The SFTAddCirculation function in core/kapp/systemAccount/systemAcount.go increments Circulation before checking the cap, enabling an int64 wraparound that makes the MaxSupply comparison permanently false. A proof-of-concept unit test is included in GHSA-mrpp-v6pg-p54x confirming the bypass; no CISA KEV listing is present at time of analysis.
Stack-based buffer overflow in TP-Link TL-MR100 V3.20 allows an adjacent unauthenticated attacker to corrupt the httpd process stack by sending a crafted encrypted payload to the /cgi/login endpoint before any authentication occurs. The flaw resides in the http_gdpr_decrypt function, which performs insufficient bounds checking on incoming data, enabling overwrite of saved control-flow data and potential arbitrary code execution in the context of the httpd process. Vendor patch is available; no public exploit code or CISA KEV listing has been identified at time of analysis.
Token minting without source debit in klever-go's percentage-transfer royalty path (`processPercentageRoyaltiesTransfer`) allows an asset owner who configures a 100% split royalty to cause the blockchain to credit the full royalty amount to an attacker-controlled address on every subsequent transfer by any holder, while the sender debit is silently skipped due to an early-return guard placed before the collection call. The exploit fires automatically on third-party transfers once the asset is configured, enabling unbounded off-books token inflation. A full Go unit test and on-chain transaction trace confirming the mint are publicly available; no CISA KEV listing exists, but the patch's inclusion of a hardcoded freeze list for six specific Klever mainnet addresses strongly implies active exploitation occurred prior to the fix.
Stack-based buffer overflow in the MongoDB BI Connector ODBC driver allows a low-privileged SQL-capable user to overwrite adjacent stack memory by submitting a positioned-cursor statement with a cursor name exceeding the size of an internal fixed-length buffer. Any application exposing MongoDB through this ODBC driver - including common BI tools such as Tableau, Excel, or MicroStrategy - is affected across all currently listed versions (CPE wildcard). Successful exploitation can crash the hosting application process and may enable unintended code execution within that process context; no public exploit or CISA KEV listing is confirmed at time of analysis.
Ledger value-creation (KLV minting) in Klever's marketplace settlement affects the klever-go node prior to v1.7.19: because referral and royalty cuts are paid in full while a negative seller remainder is silently dropped, any funded account can settle a self-dealt order whose referral% + royalty% exceeds 100% and mint the surplus into attacker-controlled addresses. Exploitation requires only an ordinary account (PR:L) reachable over the public transaction RPC (CVSS 9.6). Committed regression-test exploit code exists, and the vendor advisory (GHSA-p7gw-2pcp-5pf8) and community monitoring document active mainnet exploitation that minted tens of millions of KLV before an emergency guard was deployed, though this CVE is not listed in CISA KEV.
Stack buffer overflow in the PLANET GS-4210-16P2S managed switch web management interface exposes all firmware versions prior to 3.441b260626 to unauthenticated remote denial of service and potential memory corruption. The _readHttpParam function copies attacker-supplied HTTP query string data into a fixed-size stack buffer without enforcing size limits or guaranteeing NUL termination, after which parse_query_string processes the unbounded attacker-controlled content. No public exploit code has been identified at time of analysis and KEV status is not confirmed, but the pre-authentication network vector with no special preconditions makes this straightforwardly reachable; a vendor patch is available.
Use-after-free in the OX Dovecot Pro and Dovecot CE mail-editing code lets an authenticated user who can install a Sieve filter with the editheader extension corrupt memory during mail delivery, leaking out-of-bounds buffer contents into the delivered message and potentially crashing or executing code in the delivery process. The flaw is remotely reachable with low-privilege credentials (CVSS 9.1, scope-changed) and combines information disclosure with a denial-of-service and possible RCE. No public exploit is identified at time of analysis and it is not on CISA KEV, so risk is currently theoretical but severe.
Bitmap overflow and incorrect global accounting in the Linux kernel's percpu-km memory allocator (`mm/percpu-km`) allow a local low-privileged attacker on SMP/NUMA systems to corrupt kernel memory, with potential for privilege escalation or kernel crash. Two separate commits introduced the flaws: a63d4ac4ab609 caused `pcpu_create_chunk()` to write beyond the `chunk->populated` bitmap when `nr_units > 1`, and b539b87fed37f introduced the companion `pcpu_nr_empty_pop_pages` accounting error. Fixes have been backported to eight stable kernel branches (5.10.265, 5.15.216, 6.1.183, 6.6.151, 6.12.103, 6.18.44, 7.1.8, 7.2); no public exploit has been identified at time of analysis.
Integer truncation in the Linux kernel s390/dasd ECKD driver exposes IBM Z systems to a heap buffer overflow via a caller-controlled track range supplied to dasd_eckd_check_device_format(). The root cause is that fmt_buffer_size is declared as int while the buffer-size expression evaluates at size_t width, causing the result to be silently truncated on assignment; kzalloc() then allocates a buffer far smaller than needed, while the subsequent channel program builder operates on the untruncated track count and writes past the allocation. Systems running unpatched kernels before 6.6.151, 6.12.103, 6.18.44, 7.1.8, or 7.2 on s390 architecture face potential kernel heap corruption with consequences ranging from denial of service to local privilege escalation. No public exploit code exists and this vulnerability has not been added to the CISA KEV catalog at time of analysis.
Out-of-bounds memory corruption in the Linux kernel's vmwgfx DRM driver (vmw_external_bo_copy()) allows a local attacker with low-privilege DRM access to corrupt kernel memory via a crafted atomic display commit using an imported dma-buf framebuffer. Two distinct code paths are vulnerable: the equal-stride memcpy path suffers unsigned integer underflow when caller-supplied offsets exceed the buffer object size, and the non-equal-stride row-by-row path performs no bounds validation at all, allowing the copy loop to walk arbitrarily past the vmap end. Vendor-released patches are available across multiple stable kernel branches; no public exploit has been identified at time of analysis.
Out-of-bounds memory access in the Linux kernel's ltc4282 hwmon driver exposes systems with this hardware monitor to kernel memory disclosure or destabilization via the VGPIO minimum alarm voltage sysfs read path. A missing return statement in the driver causes the kernel to access memory beyond intended bounds when a local user reads the VGPIO channel's minimum alarm voltage attribute. Patch versions are available across multiple stable branches; no public exploit exists and EPSS sits at 0.17% (6th percentile), indicating very low current exploitation pressure despite the 7.8 CVSS score.
Out-of-bounds slab write in the Linux kernel idpf network driver lets a malicious or compromised control plane (a PF or a hypervisor's device model) corrupt kernel heap memory during interrupt-vector setup. idpf_get_reg_intr_vecs() fills the reg_vals[] array bounded only by per-chunk num_vectors from a VIRTCHNL2_OP_ALLOC_VECTORS reply, which is never reconciled against the smaller num_allocated_vectors used to size the allocation, so a reply whose chunk counts sum higher writes struct idpf_vec_regs entries past the buffer. It carries a CVSS of 9.3, but EPSS is only 0.15%, it is not on CISA KEV, and there is no public exploit identified at time of analysis.
Out-of-bounds kernel memory reads in the Linux kernel's NTFS driver arise because ntfs_read_locked_inode() copies a resident $ATTRIBUTE_LIST into ni->attr_list via a plain memcpy() with no sanity checking, while only the non-resident path was ever validated by load_attribute_list(). A crafted NTFS volume with a malformed resident attribute list is then trusted by every subsequent walk (ntfs_external_attr_find(), ntfs_inode_attach_all_extents(), ntfs_attrlist_need()), which read fixed-header fields past the buffer. The fix factors per-entry validation into ntfs_attr_list_entry_is_valid()/ntfs_attr_list_is_valid() and applies it on the resident path and inside load_attribute_list() itself; no public exploit identified at time of analysis and EPSS probability is very low (0.15%).
Out-of-bounds slab read in the Linux kernel's legacy in-kernel NTFS driver lets a crafted on-disk $ATTRIBUTE_LIST leak or crash adjacent kernel heap memory when a malicious NTFS volume is mounted and read. The flaw is in ntfs_external_attr_find(), where a look-ahead attribute-list entry is dereferenced past the end of the kvmalloc'd buffer. There is no public exploit identified at time of analysis, EPSS risk is low (0.15%, 5th percentile), and it is not listed in CISA KEV.
Out-of-bounds kernel heap read in the Linux kernel's classic in-tree NTFS driver (`fs/ntfs/`) allows a local, low-privileged user to disclose kernel memory - and potentially chain to privilege escalation - by mounting a crafted NTFS image at the filesystem layer. The flaw is a u16 integer truncation in `ntfs_check_restart_area()` that silently defeats a page-size bounds check, causing `ntfs_check_log_client_array()` to dereference up to ~64 KiB beyond an allocated heap buffer using attacker-controlled on-disk values. No public exploit code exists and no active exploitation has been confirmed; EPSS is 0.15% (5th percentile), reflecting negligible observed exploitation pressure.
Heap and integer-overflow memory corruption in the Linux kernel's userspace perf tool (perf sched) lets a malicious perf.data file corrupt memory when parsed by register_pid(). An analyst who runs 'perf sched' against an attacker-supplied perf.data trace can trigger out-of-bounds heap writes, an unchecked strcpy into a 20-byte comm buffer, and denial of service, potentially leading to code execution in the context of the user running perf. A vendor fix is available; EPSS is low (0.18%) and there is no public exploit identified at time of analysis.
Out-of-bounds heap read in the Linux kernel's perf userspace tooling (perf tools) lets a crafted perf.data file trigger memory disclosure or a crash when parsed. The flaw sits in machine__resolve(), which trusts an attacker-controlled CPU index (al->cpu) from sample data and indexes env->cpu[] without validating it against env->nr_cpus_avail; a large index reads past the heap allocation, and values like 65536 truncate to int16_t and silently resolve to CPU 0. No public exploit is identified at time of analysis, and EPSS is low (0.18%, 7th percentile).
Out-of-bounds memory access in the Linux kernel's ARM SCMI firmware subsystem allows a local low-privileged attacker on ARM-based hardware to trigger kernel memory corruption via the scmi_power_name_get() function, which fails to validate the domain number supplied by external callers. Affected kernel versions span from the introduction commit 76a6550990e2 through multiple stable branches, with patches backported to LTS lines 5.15, 6.1, 6.6, 6.12, and 6.18. No public exploit code has been identified at time of analysis, and EPSS probability is very low at 0.17% (7th percentile), indicating no current attacker tooling interest despite the 7.8 CVSS score.
Out-of-bounds write in the Linux kernel's OCFS2 cluster filesystem driver corrupts adjacent kernel memory when a low-privileged user unlinks a refcounted file whose refcount tree contains leaf blocks, triggering a fortify panic on hardened kernels. The root cause is an incorrect memset bound in `ocfs2_remove_refcount_extent()` arising from a union aliasing issue between `rf_records.rl_count` and `rf_list.l_tree_depth`. No public exploit or active exploitation has been identified; EPSS is 0.15% (5th percentile) and the vulnerability does not appear in CISA KEV, reflecting low real-world exploitation risk at time of analysis.
Out-of-bounds heap read in the Linux kernel's wcn36xx WiFi driver allows an adjacent-network attacker to corrupt Block Acknowledgment session state by sending crafted 802.11 frames that elicit a short firmware response. Kernels from 4.7 through pre-patch stable branches on devices equipped with Qualcomm WCN3660/WCN3620/WCN3680 WiFi hardware are affected. No public exploit code exists and no CISA KEV listing is present; EPSS of 0.17% (7th percentile) reflects negligible observed exploitation probability consistent with the hardware-specific attack surface.
Null-pointer dereference in the Linux kernel's btrfs LZO decompression path can crash the kernel when reading a crafted compressed extent, causing a denial-of-service. Kernels in the range starting at commit a6e66e6f8c1b685e11b778bef614480a9c1a5278 through the two fix commits are affected across multiple stable branches (5.15 and later). No public exploit code or CISA KEV listing exists at time of analysis; the EPSS score of 0.15% (5th percentile) confirms this is not yet being exploited at scale. Exploitation requires the attacker to introduce a malformed btrfs filesystem image with LZO-compressed extents that the kernel then reads.
Heap buffer overflow in the Linux kernel's Airoha (airoha_eth) network driver allows the packet-processing engine (PPE) flow-offload logic to write past an undersized allocation, corrupting kernel heap memory and crashing affected systems. The bug affects Linux 6.18.x through 6.18.39 and 6.19/7.x pre-release trees on hardware using the Airoha PPE flow-offload driver, and is triggered when airoha_ppe_foe_verify_entry() processes a flow hash at or above half the entry count. It is not in CISA KEV and has a low EPSS (0.18%), with no public exploit identified at time of analysis; impact is primarily denial of service.
Kernel memory corruption path in Linux's tunnel metadata subsystem (`tun_dst_unclone`) triggers a FORTIFY_SOURCE memcpy overflow warning when the kernel is built with clang, due to the `__counted_by` annotation on a flexible array member being evaluated as zero at copy time. Systems using GENEVE tunneling on clang-built kernels with source fortification enabled may experience kernel availability disruption if the warning escalates to a panic. No public exploit has been identified; EPSS of 0.17% at the 7th percentile reflects low exploitation probability, and the vulnerability is not listed in CISA KEV.
Out-of-bounds memory access in the Linux kernel's qede network driver (QLogic FastLinQ/QL4xxx Ethernet) occurs because the driver reads into cqe->len_list[] before validating the index, allowing a crafted or malformed completion-queue entry to trigger reads past the array bounds. The flaw affects multiple stable branches (5.15, 6.1, 6.6, 6.12, 6.17/6.18) on systems that load the qede driver, with a vendor fix that reorders the bounds check before element access. There is no public exploit identified at time of analysis, and EPSS is low at 0.17% (7th percentile).
Out-of-bounds read in the Linux kernel HID subsystem (hid_get_report) allows an adjacent, unauthenticated attacker to trigger a kernel panic or leak kernel memory by submitting a zero-length numbered HID report via a crafted Bluetooth or USB device. The vulnerability affects multiple stable kernel branches from 5.10.x through 7.1.x, with patches backported across all supported trees. No public exploit has been identified at time of analysis, and EPSS remains very low at 0.18% (7th percentile), indicating limited threat actor awareness thus far.
Out-of-bounds read in the Linux kernel's netfilter nf_conntrack_irc connection-tracking helper (parse_dcc) allows a one-byte stale read past the IRC DCC parse buffer, potentially producing an incorrect DCC IP or port in the resulting conntrack expectation. The flaw stems from parse_dcc() treating data_end as an inclusive pointer while its caller passes an exclusive one-past-the-end limit; the read currently cannot fault because irc_buffer is over-allocated by one byte and datalen is capped at MAX_SEARCH_SIZE. It affects only systems with the nf_conntrack_irc helper active, and there is no public exploit identified at time of analysis (not in CISA KEV; EPSS 0.18%).
Out-of-bounds read in the Linux kernel's batman-adv (B.A.T.M.A.N. Advanced) mesh networking subsystem exposes adjacent-network attackers to kernel memory disclosure and system crash. The vulnerability exists in batadv_dat_get_vid() within the Distributed ARP Table (DAT) component, which calls batadv_get_vid() to access the proto field of an ethernet header without first verifying that the underlying data is accessible - an obligation other call sites fulfill but this path omits. A network-adjacent unauthenticated attacker can send a crafted Layer 2 frame to trigger the flaw, yielding High confidentiality impact (kernel memory disclosure) and High availability impact (kernel panic). EPSS is 0.18% (7th percentile) and the flaw is not in CISA KEV, indicating no public exploitation at time of analysis.
Out-of-bounds read in the Linux kernel's ntfs3 LZNT decompression handler allows a local attacker with low privileges to trigger kernel memory access violations by mounting a specially crafted NTFS3 filesystem image. Affected stable branches span 5.15 through 7.x, with patched releases available across all branches. No public exploit code has been identified at time of analysis, and the EPSS score of 0.17% (7th percentile) reflects low predicted exploitation probability despite the high CVSS score of 7.8.
Out-of-bounds read in the Linux kernel's asus_atk0110 hardware monitoring driver allows a malformed ACPI GGRP firmware package to trigger kernel memory corruption. Systems running ASUS ATK0110-equipped hardware with a BIOS that returns zero-count sub-packages in its GGRP management group response are affected across a wide range of Long-Term Support and mainline kernel versions from 2.6.32 onward. Exploitation is contingent on a specific hardware/firmware defect condition rather than a direct user action, but the resulting out-of-bounds read in kernel space carries high potential impact across confidentiality, integrity, and availability. No public exploit or CISA KEV listing exists; EPSS is 0.18% (7th percentile), reflecting the niche hardware prerequisite.
Heap-based buffer overflow in openNDS before 11.0.0 allows an unauthenticated attacker positioned on the captive portal network to crash the openNDS daemon and potentially execute arbitrary code remotely. The flaw is in the redirect_to_splashpage function in http_microhttpd.c, where the query string buffer is under-allocated at QUERYMAXLEN bytes despite URL encoding expanding input by up to 1.5x - when a crafted request triggers the redirect path, the encoded data overflows the heap allocation. No public exploit identified at time of analysis, though the upstream fix commit is publicly available and exposes the exact vulnerable code path.
Remote code execution in WatchGuard Fireware OS affects the iked IKE/IPsec VPN daemon, where a memory-safety defect lets a remote unauthenticated attacker run arbitrary code by sending specially crafted network traffic to the appliance's VPN listener. The CVSS 4.0 base score of 9.3 reflects network-reachable, no-privilege, no-interaction exploitation with high confidentiality, integrity, and availability impact. No public exploit is identified at time of analysis and it is not listed in CISA KEV, but the pre-authentication RCE profile on an internet-facing firewall makes this high priority.
Out-of-bounds read in the WatchGuard Fireware OS iked (Internet Key Exchange daemon) process enables remote unauthenticated attackers to crash VPN processing by sending specially crafted network traffic, resulting in a Denial of Service condition. All Fireware OS versions appear affected per the wildcard CPE, and the vulnerability is reachable without authentication from any network path to the iked listener. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity makes this a realistic target for disrupting VPN availability on WatchGuard appliances.
Stack-based buffer overflow in the iked (IKE daemon) process of WatchGuard Fireware OS allows a remote unauthenticated attacker to crash VPN processing via specially crafted network traffic, causing a denial-of-service condition on affected Firebox appliances. Any Firebox with IPsec VPN exposed to untrusted networks is at risk across an unspecified range of Fireware OS versions. No public exploit code has been identified at time of analysis, but the CVSS 4.0 score of 8.7 with network-accessible, zero-authentication exploitation reflects meaningful operational urgency for perimeter security devices.
Remote code execution in WatchGuard Fireware OS affects the epm (Endpoint Protection Manager) service tied to the deprecated Mobile Security feature, where a stack-based buffer overflow lets an unauthenticated remote attacker run arbitrary code on the appliance. The CVSS 4.0 base score is 9.3 (critical) with a network, no-privilege, no-interaction vector. No public exploit identified at time of analysis and it is not listed in CISA KEV, but as a perimeter firewall RCE the impact is severe for any deployment still running Mobile Security.
Remote code execution in WatchGuard Fireware OS is possible via a heap overflow (CWE-122) in the iked (IKE/IPsec key management) process, letting a remote unauthenticated attacker run arbitrary code by sending specially crafted network traffic to an affected Firebox firewall. The vendor-assigned CVSS 4.0 base score is 9.3 (critical), reflecting network-reachable, no-privilege, no-interaction exploitation with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and the CVE is not in CISA KEV, but the pre-authentication nature and the perimeter role of the affected device make this a high-priority patching item.
Out-of-bounds read in the WatchGuard Fireware OS iked (IKE daemon) process allows remote unauthenticated attackers to disrupt VPN operations by sending specially crafted network packets. The flaw resides in VPN processing logic and can crash or destabilize the IKE service, cutting off IPsec/IKEv2 tunnels for connected clients and sites. No public exploit has been identified at time of analysis and CISA KEV listing is not confirmed; however, the unauthenticated network attack vector and CVSS 4.0 score of 8.7 place this in the priority triage tier for organizations relying on WatchGuard Firebox VPN connectivity.
Remote code execution in WatchGuard Fireware OS affects the iked (IKE/IPsec VPN key-exchange) daemon, where a stack-based buffer overflow lets a remote, unauthenticated attacker run arbitrary code by sending specially crafted network traffic. Because iked terminates VPN negotiations at the network edge, any Firebox appliance exposing IKE/IPsec is reachable pre-authentication. No public exploit has been identified at time of analysis and the CVE is not listed in CISA KEV, but the pre-auth RCE profile on a perimeter security device makes this a top-priority patch.
Buffer overflow in the WatchGuard Fireware OS Management Web UI allows an authenticated administrator with network access to trigger a denial-of-service condition or potentially execute arbitrary code by submitting specially crafted traffic to the management interface. The root cause is CWE-787 (out-of-bounds write) in the web-based management component, and the CVSS 4.0 vector confirms network reachability with high-privilege authentication as prerequisites. No public exploit code or active exploitation has been identified at time of analysis, though the RCE potential on a network perimeter device elevates the severity beyond what the privilege requirement alone might suggest.
Out-of-bounds read in V8, Chrome's JavaScript engine, enables remote code execution confined within the renderer sandbox on all platforms running Chrome prior to 151.0.7922.72. The flaw is triggered by a specially crafted HTML page, requiring only that a user visit a malicious site - no authentication or elevated privileges are needed from the attacker. No public exploit code has been identified and no active exploitation is confirmed; EPSS probability stands at 0.30%, aligning with SSVC's 'exploitation: none' classification despite the high CVSS score.
Stack-based buffer overflow in the Bendix EC80ESP brake ECU family enables adjacent-network attackers to crash the ECU or achieve remote code execution and arbitrary CAN bus traffic injection via a crafted payload. All known variants across both EC80ESP and EC80ESP+ product lines are affected, including J1708, 6S/6M, PLC, 2nd CAN, integrated TPMS, CAN Gateway, and 4S/4M configurations deployed on commercial vehicles. Successful exploitation could disable safety-critical functions including ABS, steering assist, speedometer, and automatic gear shifting. No public exploit has been identified at time of analysis; the flaw was disclosed by CISA ICS-CERT.
Out-of-bounds write across all Bendix EC80ESP Brake ECU variants enables an unauthenticated attacker with adjacent vehicle-network access to deliver a crafted payload that establishes an arbitrary write primitive, crashing the safety-critical brake Electronic Control Unit. Reported by ICS-CERT and documented in CISA advisory ICSA-26-237-05, all ten identified EC80ESP hardware configurations are affected with no version constraint specified in the CPE data. No public exploit code or CISA KEV listing has been identified at time of analysis, but the safety implications of a crashed brake ECU demand prioritized attention by fleet operators beyond what the base score alone conveys.
Root code execution in Unitree G1 EDU robot firmware through version 1.5.2 is achievable by proximate unauthenticated attackers via a chained BLE GATT and WiFi provisioning exploit requiring no pairing or credentials. Crafted BLE writes overflow a fixed BSS buffer in the SSID chunk accumulator, corrupting an adjacent mainloop function pointer dispatch entry; the cleanup path subsequently invokes this corrupted pointer, passing attacker-controlled data to system() as uid 0. A public proof-of-concept (UniBLEed) is available, and the CVSS 4.0 score of 7.7 reflects the adjacent attack vector and high complexity of the exploit chain.
Heap buffer overflow in rsyslog's RainerScript `replace()` function allows unauthenticated remote attackers to crash affected systems by sending crafted syslog messages. The root cause is an incorrect buffer size calculation (CWE-131) during string replacement, leading to heap memory corruption and reliable denial of service. This affects rsyslog as shipped across Red Hat Enterprise Linux versions 6 through 10; no public exploit or CISA KEV confirmation exists at time of analysis.
Heap-based buffer overflow in Adobe Substance 3D Sampler versions 5.1.3 and earlier enables arbitrary code execution at the privilege level of the current user when a crafted file is opened. The vulnerability stems from improper bounds checking during file parsing (CWE-122), allowing a heap memory region to be overwritten with attacker-controlled data. No public exploit code has been identified at time of analysis and the flaw is not listed in the CISA Known Exploited Vulnerabilities catalog, but the file-based delivery vector makes it well-suited to phishing or watering-hole campaigns targeting 3D content creators.
Stack buffer overflow in Greenbone's OpenVAS Scanner and Greenbone OS allows a remote attacker holding user-level privileges to achieve full system compromise by supplying a malicious or compromised NASL vulnerability test (VT). Both the Greenbone OS platform and the openvas-scanner engine are confirmed affected, making this a meaningful risk in any multi-user GVM deployment or environment where user accounts may be compromised. No public exploit code has been identified at time of analysis, but the network-accessible, low-complexity attack vector and high-impact outcome place this in the immediate patching tier for production scanner infrastructure.
WibuKey64.sys kernel-mode driver in Wibu-Systems WibuKey up to version 6.70 for Windows allows a local, low-privileged attacker to trigger memory boundary violations by supplying out-of-scope pointer values, with outcomes ranging from denial of service (BSOD) to full SYSTEM-level privilege escalation via kernel code execution. The CVSS Scope:Changed metric reflects the critical boundary crossing from user-space into the driver's SYSTEM-privileged kernel context, meaning successful exploitation yields complete machine control from an unprivileged account. No public exploit has been identified at time of analysis and WibuKey has not been listed in the CISA KEV catalog, but the low attack complexity makes this a high-value local privilege escalation primitive for post-compromise chains.
Denial-of-service via segmentation fault in ccoap's option parsing logic allows unauthenticated remote attackers to crash any service built on the library by sending a single malformed CoAP message. The vulnerability exists at commit 77f55c4b466e99327c24ace8a2913d3ba7e2ccd5 of the ipflavors/ccoap C library, where the option parser does not adequately validate that sufficient data is present before accessing option fields, triggering an out-of-bounds write (CWE-787). No public exploit code or CISA KEV listing is present, and EPSS probability is very low at 0.17%, though the trivial trigger condition - a single malformed UDP packet - makes opportunistic scanning straightforward against any exposed CoAP endpoint.
CVE-2026-19499 has been reported by Ubuntu but contains no available description, CVSS score, vector, or CWE data at time of analysis. The vulnerability's nature, affected component, and impact are entirely unknown from the provided intelligence. No meaningful characterization of this CVE is possible without additional data from the vendor advisory or NVD.
Heap-based buffer overflow in FFmpeg's libswscale library enables unauthenticated remote attackers to crash media-processing applications via a crafted input file. The vulnerable function ff_sws_alphablendaway, invoked during alpha channel compositing in git-master commit 722a217, mishandles attacker-controlled input and corrupts heap memory, producing a Denial of Service. No active exploitation is confirmed - EPSS stands at 0.15% (5th percentile) with no CISA KEV listing - indicating this is currently a crash risk rather than a weaponized threat.
Denial of service in Spring AI's PDF document ingestion crashes the processing thread when parsing a crafted PDF with a deeply nested or cyclic table of contents structure. Affected versions span the 1.0.x and 1.1.x release lines as well as the 2.0.0 release. An unauthenticated remote attacker who can supply a malicious PDF to an application's ingestion pipeline can trigger a StackOverflowError, halting document processing availability with no confidentiality or integrity impact. No public exploit code or CISA KEV listing has been identified at time of analysis.
Heap-based buffer overflow in the Dia diagram editor's WPG file importer allows arbitrary code execution or process crash when a user opens a crafted WPG file. The WPG color palette buffer is allocated for exactly 256 entries (768 bytes), but the COLORMAP record parser fails to validate that the supplied start index (i16) or total entry count (iNum16) stay within that bound, allowing a malicious file to drive fread() to write beyond the heap allocation. Affecting all Dia versions on the upstream master branch through at least 2026-08-21, no public exploit or patch version has been confirmed at time of analysis, though the description provides sufficient detail to construct proof-of-concept input.
Stack-based buffer overflow in Dell PowerProtect One versions 20.1.0.0 and below enables unauthenticated remote attackers to crash the service, resulting in denial of availability. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation requires no authentication and no special network positioning, making this trivially reachable in any environment where the product is exposed. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity warrants prompt patching in environments relying on this platform for data protection.
Out-of-bounds memory write in the Linux kernel's ASoC lpass-tx-macro audio codec driver allows a local low-privileged user to corrupt kernel memory via misconfigured ALSA enum kcontrol access, with potential for privilege escalation. The driver's get and put handlers for DEC0-DEC7 MODE controls incorrectly access the 8-byte integer union field instead of the 4-byte enumerated union field, writing 4 bytes beyond the intended boundary on 64-bit systems. No public exploit code has been identified at time of analysis, but the pattern mirrors two previously fixed sibling drivers (rx-macro, va-macro), confirming the root cause is well-understood.
Out-of-bounds hardware I/O reads in the Linux kernel's fbdev framebuffer subsystem allow low-privileged local users to read memory beyond valid hardware bounds, with high confidentiality and availability impact. The flaw in fb_io_read() stems from pointer desynchronization after a partial copy_to_user() transfer: the hardware source pointer advances by the full original chunk size while count is only decremented by successfully copied bytes, causing subsequent loop iterations to read from incorrect, over-advanced offsets. No public exploit or CISA KEV listing exists at time of analysis; patches are available across multiple stable kernel branches.
Out-of-bounds kernel heap write in the Linux kernel's Focaltech touchpad input driver allows local attackers to corrupt kernel memory through a signed integer underflow in the finger index variable. The `focaltech_process_rel_packet` function incorrectly handles a packet reporting finger index 0: subtracting 1 from a signed variable produces -1 rather than wrapping to a large unsigned value, bypassing the FOC_MAX_FINGERS bounds check and writing to `state->fingers[-1]`. Affected kernel versions span multiple stable branches from Linux 4.0 through the pre-patch revisions of 5.10.x, 5.15.x, 6.1.x, 6.6.x, 6.12.x, 6.18.x, 7.1.x, and 7.2; no CISA KEV listing and no public proof-of-concept exploit exist at time of analysis.
Heap buffer overflow in the Linux kernel synaptics-rmi4 driver allows local low-privileged users to overwrite kernel heap memory by exploiting stale state in the F54 diagnostics function. Affected systems must have Synaptics RMI4 touchpad hardware present and the driver loaded; exploitation involves manipulating V4L2 buffer sizes to trigger the overflow after an error condition leaves f54->report_size containing a stale value from a prior successful operation. Patches are available across all supported stable branches; no public exploit or confirmed active exploitation (CISA KEV) has been identified at time of analysis.
Heap buffer overflow in the Linux kernel's synaptics-rmi4 driver allows a local low-privileged user to trigger memory corruption by issuing VIDIOC_S_INPUT while the V4L2 diagnostic queue is actively streaming. The F54 function allocates V4L2 buffers sized to the report type at stream start; switching the input mid-stream to a larger report type overflows those buffers, enabling potential privilege escalation to root. Patches have been released across all active stable kernel branches; no public exploit code or CISA KEV listing has been identified at time of analysis.
Out-of-bounds table access in the Linux kernel fp9931 regulator driver exposes kernel memory to corruption via a malformed VPOS/VNEG voltage selector lookup table. The fp9931 driver's VPOSNEG_table[] contains two defects: a duplicate 7.04V entry that shifts all subsequent selector mappings by one, and a truncated table of only 41 entries instead of the required 64, meaning any selector value above 0x28 triggers an out-of-bounds access in kernel memory. Devices incorporating the FP9931 PMIC (a display-panel power regulator) running affected kernel versions are vulnerable; exploitation probability is very low (EPSS 0.20%, 10th percentile) with no public exploit and no confirmed active exploitation.
Out-of-bounds kernel memory read in the Linux kernel DRM log subsystem allows a local low-privileged user to potentially disclose kernel memory contents or crash the system. The flaw resides in drm_log_draw_kmsg_record(), where an unsigned integer underflow on a zero-length message causes an array access at offset UINT_MAX (0xFFFFFFFF) rather than a valid buffer position. No public exploit exists and EPSS sits at 0.20% (10th percentile), indicating low observed exploitation interest, though the kernel DRM panic-display path is reachable on any system with a GPU using the DRM framework.
Out-of-bounds write in the Linux kernel's `dev_validate_header()` network function allows a local process holding `CAP_SYS_RAWIO` to corrupt kernel memory by sending a raw packet with a short link-layer header while the target network device is concurrently reconfigured to increase `hard_header_len`. The `memset` zero-padding operation writes past the skb headroom reserved at allocation time, producing a silent memory corruption that is worse than the pre-existing `skb_under_panic()` it masks. Patches are available across multiple stable kernel branches; EPSS stands at 0.24% with no public exploit or CISA KEV listing.
Stack buffer overflow (CWE-121) in the file-level restore agent of Dell PowerProtect Data Manager versions 20.2.0.0 and below enables attackers to potentially achieve full system compromise, including code execution. The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, score 7.8) indicates local access with low privileges, while the vendor description separately references a 'high privileged remote attacker' - a direct conflict in both attack vector and privilege level requiring vendor clarification. No public exploit or CISA KEV listing exists at time of analysis.
Buffer overflow in TOTOLINK CP450 4.1.0's web CGI handler allows low-privileged remote attackers to corrupt memory and likely execute arbitrary code by supplying an oversized value to the `topicurl` argument in `/cgi-bin/cstecgi.cgi`. The CVSS 4.0 threat metric E:P confirms proof-of-concept exploit code exists, elevating this beyond a theoretical concern. No vendor patch or advisory has been published, leaving affected devices exposed with only compensating controls available.
Heap buffer overflow in zlib 1.3.1.2 through 1.3.2 allows remote attackers to corrupt memory via crafted input to applications using the non-blocking gzwrite API. The gz_vacate() function fails to bounds-check a memmove() when stale external buffer pointers are present after a write stall, reachable by calling gzprintf() or gzvprintf() in that state. A publicly available proof-of-concept exploit exists; no vendor-released patch has been identified at time of analysis.
Verifier bypass in PREVAIL, the polynomial-runtime eBPF verifier (used notably as the abstract-interpretation verifier in ebpf-for-windows), affects all versions prior to 0.2.4. When a destination register carries a non-singleton typeset - two or more simultaneously possible pointer types, e.g. {ctx, shared} or a {number, pointer} union - EbpfTransformer::add() silently skips updating the pointer offset variable, leaving a stale pre-add offset. Subsequent bounds checks reason from that stale offset and accept out-of-bounds memory accesses, so a crafted BPF program that would corrupt memory at runtime is incorrectly accepted as safe; the fix landed in 0.2.4 and no public exploit has been identified.
Heap out-of-bounds write in NGINX JavaScript (njs) xml.exclusiveC14n() allows unauthenticated remote attackers to crash NGINX worker processes or cause unbounded memory growth, with theoretical code execution that has not been demonstrated. The vulnerability is directly reachable in the nginxinc/nginx-saml reference SAML SP implementation, which passes untrusted InclusiveNamespaces/@PrefixList values to xml.exclusiveC14n() before signature verification completes - meaning no valid SAML signature is required to trigger it. Both the njs (default) and QuickJS engines are affected, with differing crash-vs-leak behavior, but both result in denial of service. No public exploit is identified at time of analysis.
Heap buffer overflow in PX4 Autopilot's sd_bench command allows adjacent unauthenticated attackers to crash the flight controller or potentially execute arbitrary code by supplying a block size parameter smaller than four bytes. The overflow occurs because a fixed four-byte block number is written into a heap allocation sized by the user-supplied block_size value - when that value is 1, 2, or 3 bytes, the write extends beyond the allocated region. No active exploitation has been confirmed (not in CISA KEV) and no EPSS score is available, but the adjacent network attack vector means exploitation is constrained to operators with direct access to the drone's MAVLink control network.
Stack-based buffer overflow in the GPU component of Google Chrome on Windows (prior to 152.0.7977.75) enables full sandbox escape and arbitrary code execution on the host operating system. Exploitation is a two-stage chained attack: an attacker must first compromise the renderer process (via a separate vulnerability or exploit), then leverage this GPU flaw to break out of Chrome's sandbox and execute code with elevated host privileges. Google has released a patch in the stable channel update for desktop; no public exploit code or CISA KEV listing has been identified at time of analysis.
Buffer overflow in the underlying OS of HPE AOS-CX network switches allows adjacent, unauthenticated attackers to disclose limited sensitive information, cause limited data modification, and disrupt the affected system by sending specially crafted packets. The CVSS 7.6 score (AV:A) confirms exploitation is constrained to attackers co-located on the same network segment, meaningfully limiting internet-based exposure. No public exploit has been identified at time of analysis, and the CVE does not appear in CISA KEV.
Silent stack-based buffer overflow in Pyramid Solutions' NetStaX EtherNet/IP Stack before v5.6.1 lets a remote attacker send an oversized Class 3 explicit-message request that overruns the application-side receive buffer without any CIP error being returned, causing memory corruption, device crash, or a potential remote code-execution path. Any industrial device embedding the affected stack for EtherNet/IP communication is exposed over the network with no authentication. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Heap-based buffer overflow in the gvfs SFTP backend (gvfsd-sftp) exposes GNOME desktop users to process-level denial of service or potential arbitrary code execution when connecting to a malicious SFTP server. The read_reply() function trusts the server-supplied response length without validating it against the client's allocated buffer, allowing a rogue server to overflow adjacent heap memory in the gvfsd-sftp daemon. No public exploit or CISA KEV listing is confirmed at time of analysis, but the high CVSS score of 8.8 and the C:H/I:H/A:H triad reflect worst-case RCE potential once a user mounts an attacker-controlled share.
Unauthenticated denial-of-service in Rockwell Automation RSLinx Classic allows a remote attacker to crash the communications service by sending a crafted CIP packet containing an oversized embedded message request. The buffer overflow (CWE-120) causes the RSLinx Classic service to terminate, requiring manual restart to restore industrial device connectivity. In OT/ICS environments where RSLinx Classic bridges engineering workstations to Allen-Bradley PLCs and HMIs, service loss can halt production operations or degrade visibility into live industrial processes. No public exploit or CISA KEV listing confirmed at time of analysis.
Unauthenticated remote denial-of-service in Rockwell Automation CompactLogix 5380 and ControlLogix 5580 industrial controllers allows a network-adjacent attacker to trigger a Major Nonrecoverable Fault (MNRF) by sending a malformed CIP message with an invalid input length, requiring a physical power cycle to restore controller operation. The vulnerability is rooted in CWE-119 (improper buffer bounds restriction) during CIP message processing on EtherNet/IP-accessible PLCs. No public exploit code or active exploitation has been identified at the time of this analysis, but the zero-prerequisite network attack surface on safety-critical industrial hardware makes this a prioritized remediation target for OT security teams.
Memory safety vulnerabilities across multiple internally discovered bugs in Firefox 154 and Firefox ESR 153.1 allow network-based attackers to potentially achieve full browser compromise through memory corruption (CWE-119). Mozilla's own advisory clusters dozens of individual Bugzilla reports - including buffer overflows and related defects - under a single advisory umbrella, noting that sufficiently motivated attackers could likely exploit some of these bugs. Vendor-released patch is available: Firefox 155 and Firefox ESR 153.2. No public exploit identified at time of analysis.
Memory corruption in Mozilla Firefox 154, Firefox ESR 153.1, and Firefox ESR 140.14 stems from a batch of internally discovered memory-safety defects that Mozilla presumes could be exploited to run arbitrary code within the browser process. The flaws were found by Mozilla's own developers and fuzzing efforts (no external report), affect the mainline and both ESR trains, and are resolved in Firefox 155, ESR 140.15, and ESR 153.2. There is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.17%, 6th percentile).
Memory-corruption defects in Mozilla Firefox 154 were discovered internally by Mozilla and bundled under CVE-2026-84142 (advisories MFSA2026-82 and MFSA2026-86), and fixed in Firefox 155. Several of the reported Bugzilla issues showed evidence of memory corruption that Mozilla presumes could have been exploited with sufficient effort to achieve code execution when a user renders malicious web content. There is no public exploit identified at time of analysis and EPSS is low (0.14%), consistent with an internally-found, pre-disclosure fix rather than active abuse.
Memory corruption in the Graphics: ImageLib component of Mozilla Firefox stems from an integer overflow when handling image data, potentially allowing remote attackers to corrupt heap memory and achieve code execution when a victim renders malicious image content. Mozilla fixed the issue in Firefox 155 and Firefox ESR 153.2 (advisories mfsa2026-82/85/86/88). It carries a critical 9.8 CVSS score, but EPSS is only 0.14% (4th percentile), it is not in CISA KEV, and no public exploit was identified at time of analysis.
Memory corruption vulnerabilities internally discovered across multiple Firefox release lines (154, ESR 153.1, ESR 140.14, ESR 115.39) could enable remote code execution when a user visits a specially crafted webpage. Mozilla's security team identified a cluster of memory safety bugs spanning 15+ tracked Bugzilla issues, several of which showed direct evidence of memory corruption sufficient to presume exploitability with sufficient attacker effort. Patches are available across all affected branches (Firefox 155, ESR 115.40, ESR 140.15, ESR 153.2); no public exploit code or CISA KEV listing is associated with this advisory.
Remote code execution in the Tenda A18 Wi-Fi router (firmware v15.13.07.09) arises from an unauthenticated buffer overflow in the fromSetCmdlineRun function, letting a remote attacker corrupt memory and run arbitrary code on the device. The CVSS 9.8 vector indicates network-reachable, no-authentication, no-interaction exploitation, and a public repository (github.com/momo8877847/Tenda-A18) appears to document the flaw, so publicly available exploit code likely exists. There is no CISA KEV listing and EPSS is low (0.30%), indicating no confirmed widespread active exploitation at this time.
Memory corruption via classic buffer overflow in WebKitGTK allows remote attackers to achieve full code execution by delivering malicious web content to a victim user. Affecting Red Hat Enterprise Linux versions 6 through 9, the vulnerability requires no authentication and no special configuration - only that a user process attacker-controlled web content through a WebKitGTK-based application. No public exploit has been identified at time of analysis, but the CVSS 8.8 High rating and full CIA triad impact make this a high-priority patching target across the affected RHEL fleet.
Integer overflow in MSI Dragon Center's NTIOLib_X64.sys kernel-mode driver (versions up to 2.0.155.0) allows local low-privileged users to corrupt kernel memory via crafted count or elementSize arguments passed to the MmioWritePath MMIO Write Path Handler. Exploitation can yield full SYSTEM-level privilege escalation on the target host. A public proof-of-concept is available, the vendor did not respond to coordinated disclosure, and no official patch has been released.
Out-of-bounds heap write in GDB's legacy STABS debug format parser allows arbitrary code execution within the GDB process when a user opens a crafted ELF binary. The root cause is a linked-list removal bug in `read_member_functions()` (gdb/stabsread.c) that retains destructor entries in the main function list after decrementing the length counter, causing the subsequent array copy to write beyond allocated bounds. Confirmed under controlled conditions to achieve command execution within GDB; no inferior process execution is required, and no public exploit code is known at time of analysis.
Out-of-bounds write in D-Link DSM-G600 firmware 1.01 exposes the device to remote memory corruption via a malformed multipart request to the /load_file.cgi endpoint. A low-privileged, network-adjacent or internet-accessible attacker can trigger CWE-787 in the Multipart Handler, potentially achieving arbitrary code execution with full confidentiality, integrity, and availability impact on the device. A public proof-of-concept exploit has been disclosed; no vendor patch has been identified, consistent with D-Link's typical end-of-life posture for legacy NAS hardware.
Stack-based buffer overflow in TOTOLINK NR1800X firmware 9.1.0u.6681_B20230703 enables remote code execution through the device's web management CGI interface. The setUploadSetting handler fails to validate the length of the FileName parameter before copying it onto the stack, allowing an attacker with low-privilege access to overwrite control data and execute arbitrary code on the router. A public proof-of-concept has been disclosed on GitHub, materially increasing exploitation risk even in the absence of a confirmed vendor patch.
Stack-based buffer overflow in D-Link DIR-825M firmware 1.1.8 enables remote code execution via the web management interface's disk formatting endpoint. The `partition` argument to the `sub_46725C` function at `/boafrm/formDiskFormat` is not bounds-checked (CWE-119), allowing a low-privileged authenticated attacker to overwrite the stack and achieve arbitrary code execution on the router. A public proof-of-concept exploit exists, substantially elevating practical risk; no CISA KEV listing has been confirmed at time of analysis.
Stack-based buffer overflow in the D-Link DIR-825M 1.1.8 LTE Module Firmware Upgrade handler allows low-privileged remote attackers to achieve remote code execution by supplying an oversized fota_url argument to /boafrm/formLtefotaUpgradeFibocom. The CVSS 4.0 vector scores this at 8.6 with subsequent-system impact (SC:H/SI:H/SA:H), reflecting the potential to compromise the attached Fibocom LTE module as well as the primary router. A public proof-of-concept exploit is available on GitHub, significantly lowering the bar for exploitation; no public patch has been identified at time of analysis.
Out-of-bounds write in Exiv2's RemoteIo::Impl::populateBlocks() affects all versions prior to 0.28.9, exploitable only when Exiv2 is invoked with a remote URL as input rather than a local file path. Memory corruption from the write could theoretically enable code execution in the Exiv2 process context if a user or automated pipeline fetches a specially crafted image from an attacker-controlled server. Fixed in the 0.28.9 release; no public exploit or KEV listing identified at time of analysis.
Out-of-bounds read in Exiv2's CrwMap::decodeBasic() function affects versions prior to 0.28.9, impacting applications that use the library to parse Canon CRW image metadata. Classified as low severity by the Exiv2 maintainers, this flaw has only been reproduced using a dedicated fuzz target - the standard exiv2 command-line tool cannot trigger it under normal operation. No public exploit exists and no active exploitation has been identified, making real-world impact minimal despite the memory safety class of defect.
Remote code execution and device takeover in the Tenda HG10 (firmware build 300001138) is possible through a stack buffer overflow in the Boa web server's formIPv6Routing handler, reachable at /boaform/admin/formIPv6Routing. An oversized destNet parameter overflows a fixed-size buffer (CWE-120), letting a remote attacker crash the device or execute arbitrary code with the web server's privileges. Publicly available exploit code exists (VulDB), though the issue is not listed in CISA KEV and no active exploitation is confirmed; EPSS is not provided.
Memory corruption in TOTOLINK A720R router firmware 4.1.5cu.630_B20250509 allows authenticated remote attackers to trigger a buffer overflow in the MAC filtering subsystem, with potential for arbitrary code execution. The vulnerable path is the `setMacFilterRules` function within `cstecgi.cgi`, exploitable by sending a crafted `desc` argument over the network. A public proof-of-concept is available on GitHub; no CISA KEV listing exists at time of analysis, but the combination of network reachability and published exploit code meaningfully elevates real-world risk.
Out-of-bounds kernel heap write in the Linux kernel's GRO (Generic Receive Offload) BIG TCP path allows corruption of memory before skb->head when aggregating oversized (>64KB) packets. The flaw stems from skb_gro_receive() using a loose headroom check introduced by the IPv4 BIG TCP support commit (b1a78b9b9886); crafted frames - for example injected via AF_PACKET with a MAC header under 8 bytes - pass validation, so ipv6_gro_complete()'s memmove() for the temporary HBH jumbo header writes before skb->head and wraps skb->mac_header. It also let software VLAN and encapsulated flows (SIT/IPv6-in-IPv4) aggregate beyond 64KB. No public exploit is identified at time of analysis and EPSS is low (0.19%), and the issue affects only older stable branches (e.g. 6.18.y), not mainline 7.0+.
Integer overflow in Klever-Go's semi-fungible token (SFT) add-quantity path prior to version 1.7.19 allows a mint-role holder to bypass a finite per-nonce MaxSupply constraint, minting approximately 9.2×10^18 tokens in a single transaction. The SFTAddCirculation function in core/kapp/systemAccount/systemAcount.go increments Circulation before checking the cap, enabling an int64 wraparound that makes the MaxSupply comparison permanently false. A proof-of-concept unit test is included in GHSA-mrpp-v6pg-p54x confirming the bypass; no CISA KEV listing is present at time of analysis.
Stack-based buffer overflow in TP-Link TL-MR100 V3.20 allows an adjacent unauthenticated attacker to corrupt the httpd process stack by sending a crafted encrypted payload to the /cgi/login endpoint before any authentication occurs. The flaw resides in the http_gdpr_decrypt function, which performs insufficient bounds checking on incoming data, enabling overwrite of saved control-flow data and potential arbitrary code execution in the context of the httpd process. Vendor patch is available; no public exploit code or CISA KEV listing has been identified at time of analysis.
Token minting without source debit in klever-go's percentage-transfer royalty path (`processPercentageRoyaltiesTransfer`) allows an asset owner who configures a 100% split royalty to cause the blockchain to credit the full royalty amount to an attacker-controlled address on every subsequent transfer by any holder, while the sender debit is silently skipped due to an early-return guard placed before the collection call. The exploit fires automatically on third-party transfers once the asset is configured, enabling unbounded off-books token inflation. A full Go unit test and on-chain transaction trace confirming the mint are publicly available; no CISA KEV listing exists, but the patch's inclusion of a hardcoded freeze list for six specific Klever mainnet addresses strongly implies active exploitation occurred prior to the fix.
Stack-based buffer overflow in the MongoDB BI Connector ODBC driver allows a low-privileged SQL-capable user to overwrite adjacent stack memory by submitting a positioned-cursor statement with a cursor name exceeding the size of an internal fixed-length buffer. Any application exposing MongoDB through this ODBC driver - including common BI tools such as Tableau, Excel, or MicroStrategy - is affected across all currently listed versions (CPE wildcard). Successful exploitation can crash the hosting application process and may enable unintended code execution within that process context; no public exploit or CISA KEV listing is confirmed at time of analysis.
Ledger value-creation (KLV minting) in Klever's marketplace settlement affects the klever-go node prior to v1.7.19: because referral and royalty cuts are paid in full while a negative seller remainder is silently dropped, any funded account can settle a self-dealt order whose referral% + royalty% exceeds 100% and mint the surplus into attacker-controlled addresses. Exploitation requires only an ordinary account (PR:L) reachable over the public transaction RPC (CVSS 9.6). Committed regression-test exploit code exists, and the vendor advisory (GHSA-p7gw-2pcp-5pf8) and community monitoring document active mainnet exploitation that minted tens of millions of KLV before an emergency guard was deployed, though this CVE is not listed in CISA KEV.
Stack buffer overflow in the PLANET GS-4210-16P2S managed switch web management interface exposes all firmware versions prior to 3.441b260626 to unauthenticated remote denial of service and potential memory corruption. The _readHttpParam function copies attacker-supplied HTTP query string data into a fixed-size stack buffer without enforcing size limits or guaranteeing NUL termination, after which parse_query_string processes the unbounded attacker-controlled content. No public exploit code has been identified at time of analysis and KEV status is not confirmed, but the pre-authentication network vector with no special preconditions makes this straightforwardly reachable; a vendor patch is available.
Use-after-free in the OX Dovecot Pro and Dovecot CE mail-editing code lets an authenticated user who can install a Sieve filter with the editheader extension corrupt memory during mail delivery, leaking out-of-bounds buffer contents into the delivered message and potentially crashing or executing code in the delivery process. The flaw is remotely reachable with low-privilege credentials (CVSS 9.1, scope-changed) and combines information disclosure with a denial-of-service and possible RCE. No public exploit is identified at time of analysis and it is not on CISA KEV, so risk is currently theoretical but severe.
Bitmap overflow and incorrect global accounting in the Linux kernel's percpu-km memory allocator (`mm/percpu-km`) allow a local low-privileged attacker on SMP/NUMA systems to corrupt kernel memory, with potential for privilege escalation or kernel crash. Two separate commits introduced the flaws: a63d4ac4ab609 caused `pcpu_create_chunk()` to write beyond the `chunk->populated` bitmap when `nr_units > 1`, and b539b87fed37f introduced the companion `pcpu_nr_empty_pop_pages` accounting error. Fixes have been backported to eight stable kernel branches (5.10.265, 5.15.216, 6.1.183, 6.6.151, 6.12.103, 6.18.44, 7.1.8, 7.2); no public exploit has been identified at time of analysis.
Integer truncation in the Linux kernel s390/dasd ECKD driver exposes IBM Z systems to a heap buffer overflow via a caller-controlled track range supplied to dasd_eckd_check_device_format(). The root cause is that fmt_buffer_size is declared as int while the buffer-size expression evaluates at size_t width, causing the result to be silently truncated on assignment; kzalloc() then allocates a buffer far smaller than needed, while the subsequent channel program builder operates on the untruncated track count and writes past the allocation. Systems running unpatched kernels before 6.6.151, 6.12.103, 6.18.44, 7.1.8, or 7.2 on s390 architecture face potential kernel heap corruption with consequences ranging from denial of service to local privilege escalation. No public exploit code exists and this vulnerability has not been added to the CISA KEV catalog at time of analysis.
Out-of-bounds memory corruption in the Linux kernel's vmwgfx DRM driver (vmw_external_bo_copy()) allows a local attacker with low-privilege DRM access to corrupt kernel memory via a crafted atomic display commit using an imported dma-buf framebuffer. Two distinct code paths are vulnerable: the equal-stride memcpy path suffers unsigned integer underflow when caller-supplied offsets exceed the buffer object size, and the non-equal-stride row-by-row path performs no bounds validation at all, allowing the copy loop to walk arbitrarily past the vmap end. Vendor-released patches are available across multiple stable kernel branches; no public exploit has been identified at time of analysis.
Out-of-bounds memory access in the Linux kernel's ltc4282 hwmon driver exposes systems with this hardware monitor to kernel memory disclosure or destabilization via the VGPIO minimum alarm voltage sysfs read path. A missing return statement in the driver causes the kernel to access memory beyond intended bounds when a local user reads the VGPIO channel's minimum alarm voltage attribute. Patch versions are available across multiple stable branches; no public exploit exists and EPSS sits at 0.17% (6th percentile), indicating very low current exploitation pressure despite the 7.8 CVSS score.
Out-of-bounds slab write in the Linux kernel idpf network driver lets a malicious or compromised control plane (a PF or a hypervisor's device model) corrupt kernel heap memory during interrupt-vector setup. idpf_get_reg_intr_vecs() fills the reg_vals[] array bounded only by per-chunk num_vectors from a VIRTCHNL2_OP_ALLOC_VECTORS reply, which is never reconciled against the smaller num_allocated_vectors used to size the allocation, so a reply whose chunk counts sum higher writes struct idpf_vec_regs entries past the buffer. It carries a CVSS of 9.3, but EPSS is only 0.15%, it is not on CISA KEV, and there is no public exploit identified at time of analysis.
Out-of-bounds kernel memory reads in the Linux kernel's NTFS driver arise because ntfs_read_locked_inode() copies a resident $ATTRIBUTE_LIST into ni->attr_list via a plain memcpy() with no sanity checking, while only the non-resident path was ever validated by load_attribute_list(). A crafted NTFS volume with a malformed resident attribute list is then trusted by every subsequent walk (ntfs_external_attr_find(), ntfs_inode_attach_all_extents(), ntfs_attrlist_need()), which read fixed-header fields past the buffer. The fix factors per-entry validation into ntfs_attr_list_entry_is_valid()/ntfs_attr_list_is_valid() and applies it on the resident path and inside load_attribute_list() itself; no public exploit identified at time of analysis and EPSS probability is very low (0.15%).
Out-of-bounds slab read in the Linux kernel's legacy in-kernel NTFS driver lets a crafted on-disk $ATTRIBUTE_LIST leak or crash adjacent kernel heap memory when a malicious NTFS volume is mounted and read. The flaw is in ntfs_external_attr_find(), where a look-ahead attribute-list entry is dereferenced past the end of the kvmalloc'd buffer. There is no public exploit identified at time of analysis, EPSS risk is low (0.15%, 5th percentile), and it is not listed in CISA KEV.
Out-of-bounds kernel heap read in the Linux kernel's classic in-tree NTFS driver (`fs/ntfs/`) allows a local, low-privileged user to disclose kernel memory - and potentially chain to privilege escalation - by mounting a crafted NTFS image at the filesystem layer. The flaw is a u16 integer truncation in `ntfs_check_restart_area()` that silently defeats a page-size bounds check, causing `ntfs_check_log_client_array()` to dereference up to ~64 KiB beyond an allocated heap buffer using attacker-controlled on-disk values. No public exploit code exists and no active exploitation has been confirmed; EPSS is 0.15% (5th percentile), reflecting negligible observed exploitation pressure.
Heap and integer-overflow memory corruption in the Linux kernel's userspace perf tool (perf sched) lets a malicious perf.data file corrupt memory when parsed by register_pid(). An analyst who runs 'perf sched' against an attacker-supplied perf.data trace can trigger out-of-bounds heap writes, an unchecked strcpy into a 20-byte comm buffer, and denial of service, potentially leading to code execution in the context of the user running perf. A vendor fix is available; EPSS is low (0.18%) and there is no public exploit identified at time of analysis.
Out-of-bounds heap read in the Linux kernel's perf userspace tooling (perf tools) lets a crafted perf.data file trigger memory disclosure or a crash when parsed. The flaw sits in machine__resolve(), which trusts an attacker-controlled CPU index (al->cpu) from sample data and indexes env->cpu[] without validating it against env->nr_cpus_avail; a large index reads past the heap allocation, and values like 65536 truncate to int16_t and silently resolve to CPU 0. No public exploit is identified at time of analysis, and EPSS is low (0.18%, 7th percentile).
Out-of-bounds memory access in the Linux kernel's ARM SCMI firmware subsystem allows a local low-privileged attacker on ARM-based hardware to trigger kernel memory corruption via the scmi_power_name_get() function, which fails to validate the domain number supplied by external callers. Affected kernel versions span from the introduction commit 76a6550990e2 through multiple stable branches, with patches backported to LTS lines 5.15, 6.1, 6.6, 6.12, and 6.18. No public exploit code has been identified at time of analysis, and EPSS probability is very low at 0.17% (7th percentile), indicating no current attacker tooling interest despite the 7.8 CVSS score.
Out-of-bounds write in the Linux kernel's OCFS2 cluster filesystem driver corrupts adjacent kernel memory when a low-privileged user unlinks a refcounted file whose refcount tree contains leaf blocks, triggering a fortify panic on hardened kernels. The root cause is an incorrect memset bound in `ocfs2_remove_refcount_extent()` arising from a union aliasing issue between `rf_records.rl_count` and `rf_list.l_tree_depth`. No public exploit or active exploitation has been identified; EPSS is 0.15% (5th percentile) and the vulnerability does not appear in CISA KEV, reflecting low real-world exploitation risk at time of analysis.
Out-of-bounds heap read in the Linux kernel's wcn36xx WiFi driver allows an adjacent-network attacker to corrupt Block Acknowledgment session state by sending crafted 802.11 frames that elicit a short firmware response. Kernels from 4.7 through pre-patch stable branches on devices equipped with Qualcomm WCN3660/WCN3620/WCN3680 WiFi hardware are affected. No public exploit code exists and no CISA KEV listing is present; EPSS of 0.17% (7th percentile) reflects negligible observed exploitation probability consistent with the hardware-specific attack surface.
Null-pointer dereference in the Linux kernel's btrfs LZO decompression path can crash the kernel when reading a crafted compressed extent, causing a denial-of-service. Kernels in the range starting at commit a6e66e6f8c1b685e11b778bef614480a9c1a5278 through the two fix commits are affected across multiple stable branches (5.15 and later). No public exploit code or CISA KEV listing exists at time of analysis; the EPSS score of 0.15% (5th percentile) confirms this is not yet being exploited at scale. Exploitation requires the attacker to introduce a malformed btrfs filesystem image with LZO-compressed extents that the kernel then reads.
Heap buffer overflow in the Linux kernel's Airoha (airoha_eth) network driver allows the packet-processing engine (PPE) flow-offload logic to write past an undersized allocation, corrupting kernel heap memory and crashing affected systems. The bug affects Linux 6.18.x through 6.18.39 and 6.19/7.x pre-release trees on hardware using the Airoha PPE flow-offload driver, and is triggered when airoha_ppe_foe_verify_entry() processes a flow hash at or above half the entry count. It is not in CISA KEV and has a low EPSS (0.18%), with no public exploit identified at time of analysis; impact is primarily denial of service.
Kernel memory corruption path in Linux's tunnel metadata subsystem (`tun_dst_unclone`) triggers a FORTIFY_SOURCE memcpy overflow warning when the kernel is built with clang, due to the `__counted_by` annotation on a flexible array member being evaluated as zero at copy time. Systems using GENEVE tunneling on clang-built kernels with source fortification enabled may experience kernel availability disruption if the warning escalates to a panic. No public exploit has been identified; EPSS of 0.17% at the 7th percentile reflects low exploitation probability, and the vulnerability is not listed in CISA KEV.
Out-of-bounds memory access in the Linux kernel's qede network driver (QLogic FastLinQ/QL4xxx Ethernet) occurs because the driver reads into cqe->len_list[] before validating the index, allowing a crafted or malformed completion-queue entry to trigger reads past the array bounds. The flaw affects multiple stable branches (5.15, 6.1, 6.6, 6.12, 6.17/6.18) on systems that load the qede driver, with a vendor fix that reorders the bounds check before element access. There is no public exploit identified at time of analysis, and EPSS is low at 0.17% (7th percentile).
Out-of-bounds read in the Linux kernel HID subsystem (hid_get_report) allows an adjacent, unauthenticated attacker to trigger a kernel panic or leak kernel memory by submitting a zero-length numbered HID report via a crafted Bluetooth or USB device. The vulnerability affects multiple stable kernel branches from 5.10.x through 7.1.x, with patches backported across all supported trees. No public exploit has been identified at time of analysis, and EPSS remains very low at 0.18% (7th percentile), indicating limited threat actor awareness thus far.
Out-of-bounds read in the Linux kernel's netfilter nf_conntrack_irc connection-tracking helper (parse_dcc) allows a one-byte stale read past the IRC DCC parse buffer, potentially producing an incorrect DCC IP or port in the resulting conntrack expectation. The flaw stems from parse_dcc() treating data_end as an inclusive pointer while its caller passes an exclusive one-past-the-end limit; the read currently cannot fault because irc_buffer is over-allocated by one byte and datalen is capped at MAX_SEARCH_SIZE. It affects only systems with the nf_conntrack_irc helper active, and there is no public exploit identified at time of analysis (not in CISA KEV; EPSS 0.18%).
Out-of-bounds read in the Linux kernel's batman-adv (B.A.T.M.A.N. Advanced) mesh networking subsystem exposes adjacent-network attackers to kernel memory disclosure and system crash. The vulnerability exists in batadv_dat_get_vid() within the Distributed ARP Table (DAT) component, which calls batadv_get_vid() to access the proto field of an ethernet header without first verifying that the underlying data is accessible - an obligation other call sites fulfill but this path omits. A network-adjacent unauthenticated attacker can send a crafted Layer 2 frame to trigger the flaw, yielding High confidentiality impact (kernel memory disclosure) and High availability impact (kernel panic). EPSS is 0.18% (7th percentile) and the flaw is not in CISA KEV, indicating no public exploitation at time of analysis.
Out-of-bounds read in the Linux kernel's ntfs3 LZNT decompression handler allows a local attacker with low privileges to trigger kernel memory access violations by mounting a specially crafted NTFS3 filesystem image. Affected stable branches span 5.15 through 7.x, with patched releases available across all branches. No public exploit code has been identified at time of analysis, and the EPSS score of 0.17% (7th percentile) reflects low predicted exploitation probability despite the high CVSS score of 7.8.
Out-of-bounds read in the Linux kernel's asus_atk0110 hardware monitoring driver allows a malformed ACPI GGRP firmware package to trigger kernel memory corruption. Systems running ASUS ATK0110-equipped hardware with a BIOS that returns zero-count sub-packages in its GGRP management group response are affected across a wide range of Long-Term Support and mainline kernel versions from 2.6.32 onward. Exploitation is contingent on a specific hardware/firmware defect condition rather than a direct user action, but the resulting out-of-bounds read in kernel space carries high potential impact across confidentiality, integrity, and availability. No public exploit or CISA KEV listing exists; EPSS is 0.18% (7th percentile), reflecting the niche hardware prerequisite.
Heap-based buffer overflow in openNDS before 11.0.0 allows an unauthenticated attacker positioned on the captive portal network to crash the openNDS daemon and potentially execute arbitrary code remotely. The flaw is in the redirect_to_splashpage function in http_microhttpd.c, where the query string buffer is under-allocated at QUERYMAXLEN bytes despite URL encoding expanding input by up to 1.5x - when a crafted request triggers the redirect path, the encoded data overflows the heap allocation. No public exploit identified at time of analysis, though the upstream fix commit is publicly available and exposes the exact vulnerable code path.
Remote code execution in WatchGuard Fireware OS affects the iked IKE/IPsec VPN daemon, where a memory-safety defect lets a remote unauthenticated attacker run arbitrary code by sending specially crafted network traffic to the appliance's VPN listener. The CVSS 4.0 base score of 9.3 reflects network-reachable, no-privilege, no-interaction exploitation with high confidentiality, integrity, and availability impact. No public exploit is identified at time of analysis and it is not listed in CISA KEV, but the pre-authentication RCE profile on an internet-facing firewall makes this high priority.
Out-of-bounds read in the WatchGuard Fireware OS iked (Internet Key Exchange daemon) process enables remote unauthenticated attackers to crash VPN processing by sending specially crafted network traffic, resulting in a Denial of Service condition. All Fireware OS versions appear affected per the wildcard CPE, and the vulnerability is reachable without authentication from any network path to the iked listener. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity makes this a realistic target for disrupting VPN availability on WatchGuard appliances.
Stack-based buffer overflow in the iked (IKE daemon) process of WatchGuard Fireware OS allows a remote unauthenticated attacker to crash VPN processing via specially crafted network traffic, causing a denial-of-service condition on affected Firebox appliances. Any Firebox with IPsec VPN exposed to untrusted networks is at risk across an unspecified range of Fireware OS versions. No public exploit code has been identified at time of analysis, but the CVSS 4.0 score of 8.7 with network-accessible, zero-authentication exploitation reflects meaningful operational urgency for perimeter security devices.
Remote code execution in WatchGuard Fireware OS affects the epm (Endpoint Protection Manager) service tied to the deprecated Mobile Security feature, where a stack-based buffer overflow lets an unauthenticated remote attacker run arbitrary code on the appliance. The CVSS 4.0 base score is 9.3 (critical) with a network, no-privilege, no-interaction vector. No public exploit identified at time of analysis and it is not listed in CISA KEV, but as a perimeter firewall RCE the impact is severe for any deployment still running Mobile Security.
Remote code execution in WatchGuard Fireware OS is possible via a heap overflow (CWE-122) in the iked (IKE/IPsec key management) process, letting a remote unauthenticated attacker run arbitrary code by sending specially crafted network traffic to an affected Firebox firewall. The vendor-assigned CVSS 4.0 base score is 9.3 (critical), reflecting network-reachable, no-privilege, no-interaction exploitation with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and the CVE is not in CISA KEV, but the pre-authentication nature and the perimeter role of the affected device make this a high-priority patching item.
Out-of-bounds read in the WatchGuard Fireware OS iked (IKE daemon) process allows remote unauthenticated attackers to disrupt VPN operations by sending specially crafted network packets. The flaw resides in VPN processing logic and can crash or destabilize the IKE service, cutting off IPsec/IKEv2 tunnels for connected clients and sites. No public exploit has been identified at time of analysis and CISA KEV listing is not confirmed; however, the unauthenticated network attack vector and CVSS 4.0 score of 8.7 place this in the priority triage tier for organizations relying on WatchGuard Firebox VPN connectivity.
Remote code execution in WatchGuard Fireware OS affects the iked (IKE/IPsec VPN key-exchange) daemon, where a stack-based buffer overflow lets a remote, unauthenticated attacker run arbitrary code by sending specially crafted network traffic. Because iked terminates VPN negotiations at the network edge, any Firebox appliance exposing IKE/IPsec is reachable pre-authentication. No public exploit has been identified at time of analysis and the CVE is not listed in CISA KEV, but the pre-auth RCE profile on a perimeter security device makes this a top-priority patch.
Buffer overflow in the WatchGuard Fireware OS Management Web UI allows an authenticated administrator with network access to trigger a denial-of-service condition or potentially execute arbitrary code by submitting specially crafted traffic to the management interface. The root cause is CWE-787 (out-of-bounds write) in the web-based management component, and the CVSS 4.0 vector confirms network reachability with high-privilege authentication as prerequisites. No public exploit code or active exploitation has been identified at time of analysis, though the RCE potential on a network perimeter device elevates the severity beyond what the privilege requirement alone might suggest.
Out-of-bounds read in V8, Chrome's JavaScript engine, enables remote code execution confined within the renderer sandbox on all platforms running Chrome prior to 151.0.7922.72. The flaw is triggered by a specially crafted HTML page, requiring only that a user visit a malicious site - no authentication or elevated privileges are needed from the attacker. No public exploit code has been identified and no active exploitation is confirmed; EPSS probability stands at 0.30%, aligning with SSVC's 'exploitation: none' classification despite the high CVSS score.
Stack-based buffer overflow in the Bendix EC80ESP brake ECU family enables adjacent-network attackers to crash the ECU or achieve remote code execution and arbitrary CAN bus traffic injection via a crafted payload. All known variants across both EC80ESP and EC80ESP+ product lines are affected, including J1708, 6S/6M, PLC, 2nd CAN, integrated TPMS, CAN Gateway, and 4S/4M configurations deployed on commercial vehicles. Successful exploitation could disable safety-critical functions including ABS, steering assist, speedometer, and automatic gear shifting. No public exploit has been identified at time of analysis; the flaw was disclosed by CISA ICS-CERT.
Out-of-bounds write across all Bendix EC80ESP Brake ECU variants enables an unauthenticated attacker with adjacent vehicle-network access to deliver a crafted payload that establishes an arbitrary write primitive, crashing the safety-critical brake Electronic Control Unit. Reported by ICS-CERT and documented in CISA advisory ICSA-26-237-05, all ten identified EC80ESP hardware configurations are affected with no version constraint specified in the CPE data. No public exploit code or CISA KEV listing has been identified at time of analysis, but the safety implications of a crashed brake ECU demand prioritized attention by fleet operators beyond what the base score alone conveys.
Root code execution in Unitree G1 EDU robot firmware through version 1.5.2 is achievable by proximate unauthenticated attackers via a chained BLE GATT and WiFi provisioning exploit requiring no pairing or credentials. Crafted BLE writes overflow a fixed BSS buffer in the SSID chunk accumulator, corrupting an adjacent mainloop function pointer dispatch entry; the cleanup path subsequently invokes this corrupted pointer, passing attacker-controlled data to system() as uid 0. A public proof-of-concept (UniBLEed) is available, and the CVSS 4.0 score of 7.7 reflects the adjacent attack vector and high complexity of the exploit chain.
Heap buffer overflow in rsyslog's RainerScript `replace()` function allows unauthenticated remote attackers to crash affected systems by sending crafted syslog messages. The root cause is an incorrect buffer size calculation (CWE-131) during string replacement, leading to heap memory corruption and reliable denial of service. This affects rsyslog as shipped across Red Hat Enterprise Linux versions 6 through 10; no public exploit or CISA KEV confirmation exists at time of analysis.
Heap-based buffer overflow in Adobe Substance 3D Sampler versions 5.1.3 and earlier enables arbitrary code execution at the privilege level of the current user when a crafted file is opened. The vulnerability stems from improper bounds checking during file parsing (CWE-122), allowing a heap memory region to be overwritten with attacker-controlled data. No public exploit code has been identified at time of analysis and the flaw is not listed in the CISA Known Exploited Vulnerabilities catalog, but the file-based delivery vector makes it well-suited to phishing or watering-hole campaigns targeting 3D content creators.
Stack buffer overflow in Greenbone's OpenVAS Scanner and Greenbone OS allows a remote attacker holding user-level privileges to achieve full system compromise by supplying a malicious or compromised NASL vulnerability test (VT). Both the Greenbone OS platform and the openvas-scanner engine are confirmed affected, making this a meaningful risk in any multi-user GVM deployment or environment where user accounts may be compromised. No public exploit code has been identified at time of analysis, but the network-accessible, low-complexity attack vector and high-impact outcome place this in the immediate patching tier for production scanner infrastructure.
WibuKey64.sys kernel-mode driver in Wibu-Systems WibuKey up to version 6.70 for Windows allows a local, low-privileged attacker to trigger memory boundary violations by supplying out-of-scope pointer values, with outcomes ranging from denial of service (BSOD) to full SYSTEM-level privilege escalation via kernel code execution. The CVSS Scope:Changed metric reflects the critical boundary crossing from user-space into the driver's SYSTEM-privileged kernel context, meaning successful exploitation yields complete machine control from an unprivileged account. No public exploit has been identified at time of analysis and WibuKey has not been listed in the CISA KEV catalog, but the low attack complexity makes this a high-value local privilege escalation primitive for post-compromise chains.
Denial-of-service via segmentation fault in ccoap's option parsing logic allows unauthenticated remote attackers to crash any service built on the library by sending a single malformed CoAP message. The vulnerability exists at commit 77f55c4b466e99327c24ace8a2913d3ba7e2ccd5 of the ipflavors/ccoap C library, where the option parser does not adequately validate that sufficient data is present before accessing option fields, triggering an out-of-bounds write (CWE-787). No public exploit code or CISA KEV listing is present, and EPSS probability is very low at 0.17%, though the trivial trigger condition - a single malformed UDP packet - makes opportunistic scanning straightforward against any exposed CoAP endpoint.
CVE-2026-19499 has been reported by Ubuntu but contains no available description, CVSS score, vector, or CWE data at time of analysis. The vulnerability's nature, affected component, and impact are entirely unknown from the provided intelligence. No meaningful characterization of this CVE is possible without additional data from the vendor advisory or NVD.
Heap-based buffer overflow in FFmpeg's libswscale library enables unauthenticated remote attackers to crash media-processing applications via a crafted input file. The vulnerable function ff_sws_alphablendaway, invoked during alpha channel compositing in git-master commit 722a217, mishandles attacker-controlled input and corrupts heap memory, producing a Denial of Service. No active exploitation is confirmed - EPSS stands at 0.15% (5th percentile) with no CISA KEV listing - indicating this is currently a crash risk rather than a weaponized threat.
Denial of service in Spring AI's PDF document ingestion crashes the processing thread when parsing a crafted PDF with a deeply nested or cyclic table of contents structure. Affected versions span the 1.0.x and 1.1.x release lines as well as the 2.0.0 release. An unauthenticated remote attacker who can supply a malicious PDF to an application's ingestion pipeline can trigger a StackOverflowError, halting document processing availability with no confidentiality or integrity impact. No public exploit code or CISA KEV listing has been identified at time of analysis.
Heap-based buffer overflow in the Dia diagram editor's WPG file importer allows arbitrary code execution or process crash when a user opens a crafted WPG file. The WPG color palette buffer is allocated for exactly 256 entries (768 bytes), but the COLORMAP record parser fails to validate that the supplied start index (i16) or total entry count (iNum16) stay within that bound, allowing a malicious file to drive fread() to write beyond the heap allocation. Affecting all Dia versions on the upstream master branch through at least 2026-08-21, no public exploit or patch version has been confirmed at time of analysis, though the description provides sufficient detail to construct proof-of-concept input.
Stack-based buffer overflow in Dell PowerProtect One versions 20.1.0.0 and below enables unauthenticated remote attackers to crash the service, resulting in denial of availability. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation requires no authentication and no special network positioning, making this trivially reachable in any environment where the product is exposed. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity warrants prompt patching in environments relying on this platform for data protection.
Out-of-bounds memory write in the Linux kernel's ASoC lpass-tx-macro audio codec driver allows a local low-privileged user to corrupt kernel memory via misconfigured ALSA enum kcontrol access, with potential for privilege escalation. The driver's get and put handlers for DEC0-DEC7 MODE controls incorrectly access the 8-byte integer union field instead of the 4-byte enumerated union field, writing 4 bytes beyond the intended boundary on 64-bit systems. No public exploit code has been identified at time of analysis, but the pattern mirrors two previously fixed sibling drivers (rx-macro, va-macro), confirming the root cause is well-understood.
Out-of-bounds hardware I/O reads in the Linux kernel's fbdev framebuffer subsystem allow low-privileged local users to read memory beyond valid hardware bounds, with high confidentiality and availability impact. The flaw in fb_io_read() stems from pointer desynchronization after a partial copy_to_user() transfer: the hardware source pointer advances by the full original chunk size while count is only decremented by successfully copied bytes, causing subsequent loop iterations to read from incorrect, over-advanced offsets. No public exploit or CISA KEV listing exists at time of analysis; patches are available across multiple stable kernel branches.
Out-of-bounds kernel heap write in the Linux kernel's Focaltech touchpad input driver allows local attackers to corrupt kernel memory through a signed integer underflow in the finger index variable. The `focaltech_process_rel_packet` function incorrectly handles a packet reporting finger index 0: subtracting 1 from a signed variable produces -1 rather than wrapping to a large unsigned value, bypassing the FOC_MAX_FINGERS bounds check and writing to `state->fingers[-1]`. Affected kernel versions span multiple stable branches from Linux 4.0 through the pre-patch revisions of 5.10.x, 5.15.x, 6.1.x, 6.6.x, 6.12.x, 6.18.x, 7.1.x, and 7.2; no CISA KEV listing and no public proof-of-concept exploit exist at time of analysis.
Heap buffer overflow in the Linux kernel synaptics-rmi4 driver allows local low-privileged users to overwrite kernel heap memory by exploiting stale state in the F54 diagnostics function. Affected systems must have Synaptics RMI4 touchpad hardware present and the driver loaded; exploitation involves manipulating V4L2 buffer sizes to trigger the overflow after an error condition leaves f54->report_size containing a stale value from a prior successful operation. Patches are available across all supported stable branches; no public exploit or confirmed active exploitation (CISA KEV) has been identified at time of analysis.
Heap buffer overflow in the Linux kernel's synaptics-rmi4 driver allows a local low-privileged user to trigger memory corruption by issuing VIDIOC_S_INPUT while the V4L2 diagnostic queue is actively streaming. The F54 function allocates V4L2 buffers sized to the report type at stream start; switching the input mid-stream to a larger report type overflows those buffers, enabling potential privilege escalation to root. Patches have been released across all active stable kernel branches; no public exploit code or CISA KEV listing has been identified at time of analysis.
