Out-of-bounds read in Microsoft Office and SharePoint Server exposes local memory contents to an unauthorized attacker, resulting in information disclosure. The vulnerability (CWE-125) is triggered when a user opens a specially crafted Office document, making exploitation dependent on user interaction rather than remote network access. No active exploitation has been confirmed - CISA KEV does not list this CVE, SSVC rates exploitation as none, and EPSS probability sits at 0.51% (40th percentile), collectively indicating low real-world threat activity despite the wide deployment footprint of affected products.
Out-of-bounds read (CWE-125) in Microsoft Office's file parsing logic exposes potentially sensitive in-memory data to a local attacker when a victim opens a specially crafted document, affecting Windows and macOS Office editions as well as Microsoft SharePoint Server. The CVSS 5.5 Medium score reflects a local-only attack vector with mandatory user interaction, confining impact to information disclosure with no integrity or availability consequence. No public exploit code exists, CISA SSVC classifies exploitation as 'none' with no automation potential, and the EPSS of 0.51% (40th percentile) confirms low current exploitation probability.
Out-of-bounds read in Microsoft Excel's file parsing engine exposes sensitive memory contents when a victim opens a specially crafted workbook, affecting Excel 2016 through Office LTSC 2024 and Office Online Server across both Windows and macOS platforms. The CVSS vector (AV:L/UI:R/C:H/I:N/A:N) confirms impact is limited to confidentiality loss - no code execution results - and requires local user interaction to trigger. No public exploit has been identified and CISA has not listed this in KEV; with an EPSS of 0.46% and SSVC exploitation status of none, this is appropriate for standard patch cycle prioritization rather than emergency response.
Out-of-bounds read in Microsoft Excel and related Office products exposes adjacent process memory to local information disclosure when a user opens a specially crafted spreadsheet file. The flaw spans a broad set of Microsoft Office versions across Windows and macOS - including Excel 2016, Office 2019, LTSC 2021/2024, Microsoft 365 Apps for Enterprise, and Office Online Server - with vendor-released patches now available for all affected builds. No active exploitation has been confirmed by CISA KEV, and EPSS places exploitation probability at 0.35% (27th percentile), consistent with SSVC's assessment of no current exploitation and non-automatable delivery.
Out-of-bounds read in the Windows Remote Desktop Protocol (RDP) stack enables unauthenticated network attackers to disclose high-confidentiality memory contents from affected Windows systems, contingent on user interaction during an RDP session. The flaw (CWE-125) spans Windows 10 builds 1607 through 22H2, Windows 11 24H2 through 26H1, and Windows Server 2012 through 2025. No active exploitation is confirmed by CISA KEV, SSVC rates it non-automatable with partial technical impact, and EPSS sits at 0.67% (48th percentile), indicating moderate-to-low near-term exploitation probability despite the high confidentiality impact in the CVSS score.
Privilege escalation via heap-based buffer overflow in the Windows NTFS filesystem driver affects a broad range of Windows 10, Windows 11, and Windows Server versions, requiring only physical access to the target device - no OS credentials needed. An attacker with hands-on access to the hardware can trigger a heap overflow in NTFS processing to gain elevated privileges, potentially achieving full system compromise (High C/I/A). No public exploit code has been identified and this CVE is not listed in the CISA KEV catalog, but the combination of zero authentication requirements and critical-level impact makes it a realistic threat for physically accessible endpoints. A vendor-supplied patch is available via the Microsoft Security Response Center.
Heap-based buffer overflow in the Windows Resilient File System (ReFS) driver enables an unauthorized attacker with physical access to the target machine to execute arbitrary code, achieving full compromise of confidentiality, integrity, and availability. The vulnerability spans a wide range of Windows 10, Windows 11, and Windows Server releases from 2016 through 2025. No public exploit or active exploitation has been identified (SSVC: Exploitation none), and Microsoft has released patches; however, the physical attack vector (AV:P) is the dominant risk-shaping factor.
Denial of service in Windows Hyper-V allows an authorized, adjacent-network attacker to crash or disrupt the hypervisor by triggering a buffer over-read (CWE-126). Affected platforms span Windows 10, Windows 11, and Windows Server 2012 through 2025, covering a broad slice of Microsoft's enterprise footprint. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but a vendor-issued patch is available via Microsoft MSRC.
Buffer over-read in the Windows Kernel exposes kernel memory contents to locally authenticated, low-privilege attackers across a broad range of Windows 10, Windows 11, and Windows Server releases. The flaw (CWE-126) allows out-of-bounds memory reads within the kernel address space, resulting in high-confidence confidentiality impact with no integrity or availability consequence. No public exploit code has been identified and CISA SSVC assessment confirms no active exploitation at time of analysis, though the wide deployment footprint of affected Windows versions makes prompt patching a sensible priority.
Out-of-bounds read in HTTP.sys, the Windows kernel-mode HTTP driver, enables a local low-privileged attacker to disclose sensitive kernel memory contents on Windows 11 and Windows Server 2025. The CVSS vector (AV:L/PR:L) confirms exploitation is strictly local and requires an authenticated session - no remote or unauthenticated attack path exists. Microsoft has released patched builds; no active exploitation has been identified (SSVC Exploitation: none; EPSS 0.41%, 33rd percentile), and this vulnerability is not listed in CISA KEV.
Out-of-bounds read in usbaudio.sys (Windows USB Audio Class driver) exposes kernel memory contents to attackers with physical device access across Windows 10, Windows 11, and Windows Server 2012 through 2025. An attacker who can physically connect a crafted USB audio device causes the driver to read beyond an allocated buffer, potentially leaking sensitive kernel memory to the attacker. No public exploit exists and no active exploitation has been identified; SSVC rates this as non-automatable with partial technical impact, placing it firmly in the lower-urgency tier despite its wide platform coverage.
Windows Print Spooler Components on multiple Windows 10, 11, and Server editions contain a buffer over-read flaw (CWE-126) that allows a locally authenticated attacker with low privileges to disclose sensitive memory contents. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms exploitation requires local access and a standard user account, limiting the attack surface to insiders or already-compromised endpoints. No public exploit or active exploitation has been identified at time of analysis, and EPSS at 0.30% (22nd percentile) alongside SSVC exploitation status of 'none' together indicate low near-term exploitation probability.
Out-of-bounds memory read in the Windows Desktop Window Manager (DWM) Core Library enables a locally authenticated, low-privileged user to disclose sensitive memory contents across a wide range of Windows client and server versions. The flaw is reachable by any standard user account without administrative rights, making it relevant in multi-user, shared workstation, and terminal services environments. No active exploitation is confirmed - CISA SSVC rates exploitation as 'none', EPSS sits at 0.31% (22nd percentile), and no KEV listing exists - but the broad affected surface spanning Windows 10 through Windows 11 and Server 2025 warrants timely patching.
Out-of-bounds read in the Windows Cloud Files Mini Filter Driver (cldflt.sys) exposes kernel memory contents to local attackers with standard user privileges. Affected across Windows 10 (1809 through 22H2), Windows 11 (24H2 through 26H1), and Windows Server 2019 through 2025, the vulnerability allows an authorized local account to read beyond allocated buffer boundaries in the driver that underpins cloud sync features such as OneDrive Files On-Demand. No public exploit identified at time of analysis; EPSS is 0.31% (22nd percentile) and SSVC rates exploitation as none, making this a moderate patch priority rather than an emergency response.
Local information disclosure in the Windows Container Isolation FS Filter Driver (unionfs.sys) on Windows 11 version 26H1 allows an authorized low-privileged user to read memory outside intended bounds and disclose sensitive kernel or process data. The flaw was reported by Microsoft, a vendor patch is available, and there is no public exploit identified at time of analysis. CVSS 7.1 (AV:L) reflects local access with low privileges but high confidentiality impact.
Buffer over-read in the Windows NTFS kernel driver exposes adjacent memory contents to a local attacker holding a standard user account across a broad range of Windows 10, 11, and Server releases. Exploitation is constrained to AV:L/PR:L, meaning an attacker must already have interactive or programmatic local access before triggering the CWE-126 condition - making this a post-compromise reconnaissance primitive rather than an initial-access vector. EPSS stands at 0.31% (22nd percentile) and SSVC confirms no known exploitation activity, placing this at low operational urgency despite the High confidentiality impact rating.
Privilege escalation to SYSTEM level is achievable in Windows Spaceport.sys - the kernel-mode Storage Spaces port driver - across a wide range of Windows 10, Windows 11, and Windows Server releases, when an attacker has physical access to the target machine. An integer overflow or wraparound in the driver's arithmetic logic (CWE-190) can corrupt kernel memory structures, enabling full compromise of confidentiality, integrity, and availability. No public exploit identified at time of analysis, and SSVC confirms exploitation status as none, but the Technical Impact rating is total, meaning successful exploitation fully compromises the affected system.
Privilege escalation to SYSTEM level is achievable in the Windows USB Video Class (UVC) driver across a broad swath of Windows 10, 11, and Server editions via physical connection of a malicious USB device. The heap-based buffer overflow (CWE-122) is triggered when the driver processes attacker-controlled UVC descriptors from a crafted device, corrupting kernel heap memory. No active exploitation is confirmed (absent from CISA KEV, SSVC exploitation=none), and EPSS sits at 0.37% (29th percentile), consistent with the physical access barrier that makes mass exploitation impractical.
Integer overflow in Windows Storage Spaces Direct enables an unauthenticated attacker with physical access to execute arbitrary code on affected Windows client and server platforms. The CVSS vector (AV:P/AC:L/PR:N/UI:N, C:H/I:H/A:H) confirms that no credentials are required but direct physical presence at the target hardware is mandatory, substantially narrowing the realistic attacker pool. No public exploit identified at time of analysis; SSVC rates exploitation as 'none' and EPSS stands at 0.33% (26th percentile), consistent with a physical-vector vulnerability not currently observed in opportunistic campaigns.
Out-of-bounds read in the Windows USB Audio Class driver (usbaudio.sys) enables physical attackers to disclose kernel memory contents across a broad range of Windows 10, Windows 11, and Windows Server releases. Exploitation requires plugging a crafted USB audio device into the target machine, making remote attack impossible by design. No public exploit exists and SSVC exploitation status is confirmed as none, though the High confidentiality impact rating reflects that kernel memory disclosure can expose sensitive in-memory data if triggered.
Out-of-bounds read in the Windows Kernel (CWE-125) enables a locally authenticated attacker with standard user privileges to bypass a kernel security feature and read kernel memory contents. Confirmed by Microsoft (MSRC) across Windows 10, Windows 11, and Windows Server 2012 through 2025 editions, with patches available for all affected builds. No public exploit code and no CISA KEV listing exist at time of analysis; EPSS at 0.29% (20th percentile) and SSVC exploitation status of 'none' together signal low current exploitation activity, though the kernel memory disclosure primitive is a classic KASLR-defeat building block in chained exploits.
Information disclosure in Microsoft Office (Microsoft 365 Apps, Office 2016/2019, Office LTSC 2021/2024, and Office for Mac) via an out-of-bounds read (CWE-125) lets an attacker leak sensitive memory contents when a victim opens a maliciously crafted document. The CVSS 3.1 base score is 7.1 (AV:L/AC:L/PR:N/UI:R), reflecting local exploitation that requires user interaction but no prior authentication. Microsoft is the reporting source and has published a fix; there is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Out-of-bounds read in Microsoft Excel's spreadsheet parser (CWE-125) exposes affected systems to both local information disclosure and application crash when a victim opens a specially crafted file, spanning Excel 2016 through Office LTSC 2024 and Office 365 for Mac. The CVSS vector (AV:L/UI:R/A:H) reveals that while the CVE description emphasizes information disclosure, the primary real-world impact is application availability - the invalid memory read can crash Excel (A:H), with incidental memory content leakage (C:L) as a secondary effect. No public exploit code has been identified at time of analysis and CISA SSVC assigns exploitation status of none, consistent with a low EPSS score of 0.31% at the 23rd percentile.
Heap-based buffer overflow in Microsoft Office Excel triggers a local information disclosure when a target user opens a maliciously crafted document. Affecting Excel 2016 through Office LTSC 2024 and Microsoft 365 Apps for Enterprise on both Windows and macOS, the vulnerability yields only limited confidentiality impact (C:L) with no integrity or availability consequence, placing it in the Low severity tier at CVSS 3.3. No public exploit code exists and no active exploitation has been confirmed - CISA's SSVC framework rates exploitation as none, automatable as no, and technical impact as partial, consistent with the low EPSS probability of 0.27% (19th percentile).
Heap-based buffer overflow in the Windows Kernel (CWE-122) enables an unauthenticated attacker with physical access to escalate privileges to SYSTEM level across a broad range of Windows 10, Windows 11, and Windows Server editions. The physical attack vector (AV:P) constrains the threat surface significantly, and SSVC rates exploitation as none with no public exploit identified at time of analysis. Despite total technical impact potential confirmed by both CVSS C:H/I:H/A:H metrics and SSVC technical impact rating, real-world risk is concentrated in physically accessible deployment scenarios such as kiosks, field laptops, or shared terminals.
Out-of-bounds read in the Windows TCP/IP stack exposes kernel or process memory to locally authenticated low-privileged users across a broad range of Windows 10, Windows 11, and Windows Server releases spanning from Server 2012 through Server 2025. The CWE-125 root cause allows an authorized local attacker with standard user credentials to read memory regions outside allocated buffer boundaries in the TCP/IP component, yielding high-confidentiality-impact information disclosure with no integrity or availability consequence. No public exploit code exists and no active exploitation has been identified (EPSS: 0.31%, 22nd percentile; SSVC exploitation status: none), placing this in a lower-priority remediation tier despite its exceptionally broad product footprint.
Privilege escalation to full system control is achievable in Windows Storage Spaces Direct via a CWE-190 integer overflow that causes arithmetic wraparound, exploitable by an attacker with physical access to affected hardware. The flaw spans Windows 10 (versions 1607-22H2), Windows 11 (24H2-26H1), and Windows Server 2016 through 2025, representing a broad Microsoft platform footprint. Despite the C:H/I:H/A:H impact profile confirmed by SSVC as 'technical impact: total,' the physical access prerequisite (AV:P) is a hard constraint; SSVC additionally confirms exploitation status as none, no public exploit code exists, and EPSS sits at 0.31% (23rd percentile), making this a low operational priority for most organizations.
Buffer over-read in Fortinet FortiOS and FortiProxy exposes sensitive memory contents to authenticated network attackers across multiple product lines including FortiPAM and FortiSwitchManager. The flaw, rooted in CWE-126 (buffer over-read), allows low-privileged remote users to read beyond allocated buffer boundaries, resulting in partial information disclosure with no integrity or availability impact. No active exploitation confirmed in CISA KEV, but the CVSS temporal vector includes E:P indicating proof-of-concept exploit code exists, and an official fix is available per RL:O.
FortiOS across the 7.2, 7.4, and 7.6 release trains leaks portions of device runtime memory to authenticated remote attackers via a buffer over-read in redirect response handling. Exploitation requires valid credentials but no elevated privileges, and proof-of-concept code exists (CVSS temporal E:P). An official vendor fix is confirmed available (RL:O), though unpatched instances of FortiOS 7.2.x, 7.4.0-7.4.8, and 7.6.0-7.6.2 remain at risk of sensitive memory disclosure - a consequential exposure given that FortiOS processes session tokens, credentials, and cryptographic material at runtime.
Information disclosure in Fortinet FortiAuthenticator (6.5 all versions and 6.6.0–6.6.2) lets a remote unauthenticated attacker read out-of-bounds memory via a specially crafted request, exposing sensitive in-memory data. The CVSS temporal metrics (E:F, RC:C) indicate a functional, confirmed exploit is understood by the vendor, and an official fix is available (RL:O). No CISA KEV listing is present, so this is not confirmed as actively exploited despite the mature exploit signal.
Stack-based buffer overflow in Fortinet FortiOS, FortiPAM, FortiProxy, and FortiSASE enables arbitrary code execution for a privileged authenticated attacker capable of bypassing ASLR and stack canary protections via crafted HTTP requests. The CVSS temporal metric E:P confirms proof-of-concept exploit code exists, and RL:O confirms an official patch has been released by Fortinet (advisory FG-IR-26-148). This vulnerability is not listed in CISA KEV at time of analysis, and the dual prerequisites of privileged access plus memory-protection bypass substantially constrain real-world exploitability despite the critical CIA impact triad.
Denial-of-service in Rockwell Automation CompactLogix/GuardLogix 5380, CompactLogix 5480, and ControlLogix/GuardLogix 5580 controllers running boot firmware below version 1.072 lets a remote unauthenticated attacker write malformed file data that forces the device into a major non-recoverable fault (MNRF), halting the controlled process until manual recovery. The flaw carries a CVSS 4.0 base of 9.2 driven purely by availability impact (no data confidentiality or integrity loss) and requires no authentication or user interaction. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial-of-service in Rockwell Automation Logix programmable controllers allows a remote unauthenticated attacker to write invalid file data that forces the device into a Major Non-Recoverable Fault (MNRF), halting the industrial process it controls. Rated CVSS 4.0 9.2 (Critical) with availability as the sole impact, the flaw is a CWE-120 buffer overflow reachable over the network with no privileges or user interaction. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, but the low attack complexity makes it a high-priority patch for OT environments.
Remote denial-of-service in Rockwell Automation CompactLogix 5370, Compact GuardLogix 5370, ControlLogix 5570, and GuardLogix 5570 controllers allows a remote user to push a malformed project file that forces the controller into a Major Non-Recoverable Fault (MNRF), halting the controlled process until manual recovery. The CVSS 4.0 score of 9.2 reflects high availability impact on both the controller and the downstream physical process (VA:H/SA:H) with no authentication or user interaction required per the vendor vector. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV, but the loss of a safety-rated (GuardLogix) controller makes availability the dominant concern.
Out-of-bounds read in Citrix Secure Access Client for Windows (all versions before 26.6.1.20) enables a local low-privileged attacker to read memory beyond an allocated buffer boundary, resulting in high confidentiality impact with no integrity or availability consequence. The CVSS 4.0 score of 6.8 reflects the local attack vector and low-privilege requirement, meaning an attacker must already hold a foothold on the endpoint. No public exploit code and no active exploitation (CISA KEV) have been identified at time of analysis.
Out-of-bounds read in libsoup 3.6.6 exposes WebSocket clients to memory disclosure and crashes when connecting to malicious servers. The incomplete fix for CVE-2026-0716 (commit 6ff7ef0) placed the integer overflow guard exclusively inside the masked-frame branch, leaving the unmasked server-to-client frame path entirely unprotected - allowing a crafted payload length near UINT64_MAX to bypass the guard entirely. No public exploit code or active exploitation (CISA KEV) has been identified, but the CVSS AC:H rating reflects the non-trivial preconditions: a specific client configuration and attacker-controlled server are both required.
Buffer overflow in SUSE Virtual Machine Driver Pack allows a local attacker with registry modification rights to corrupt driver integrity. Affected are all versions of the pack before upstream commit e7a602ec232756ead019bdf19d6d3b9d010cc94b, targeting virtualized guest environments running SUSE's paravirtual drivers. No public exploit exists and the vendor explicitly states no feasible exploitation path is currently known; no public exploit identified at time of analysis.
Out-of-bounds read and write conditions exist in the `wrap_lines_measure` function, as tracked under GHSA-pjjp-65r7-ppgm and reported by Ubuntu. Memory corruption of this class - simultaneous OOB read and write - typically enables attackers to leak sensitive memory contents and corrupt heap or stack state, potentially leading to arbitrary code execution or process crash depending on exploitability conditions. No CVSS vector, EPSS score, KEV status, or POC availability data was supplied, so severity and real-world risk cannot be quantified with confidence at this time.
Out-of-bounds bit clear operations in a Matroska container format parser allow processing of maliciously crafted media files containing negative ReadOrder field values to corrupt memory. The vulnerability arises when a negative integer ReadOrder value is used without adequate sign checking, causing bit-clear write operations to target memory locations outside the intended buffer boundary. Affected deployments include software in the Ubuntu ecosystem that parses Matroska (.mkv/.webm) files; no public exploit has been identified at time of analysis and CISA KEV status is not confirmed.
Out-of-bounds read in Blender 3.0.0 through 5.1.2 allows an attacker to crash the application or disclose heap memory contents by convincing a user to open a specially crafted .blend file containing a malicious member_index value in the SDNA block. The vulnerability stems from missing bounds validation on a signed short index used directly as an array subscript in sdna_expand_names(), enabling both denial-of-service via SIGSEGV and limited heap memory disclosure. No public exploit code or active exploitation has been identified at time of analysis, but the file-based attack vector makes social engineering a realistic delivery mechanism.
Stack-based buffer overflow in gawk's readdir extension (extension/readdir.c, ftype() routine) affects all gawk releases through version 5.4.0, enabling a local attacker to crash the process and theoretically achieve code execution. The RCE angle is explicitly unconfirmed by the reporter (CERT-PL), making denial-of-service the primary demonstrated impact at this time. No public exploit identified at time of analysis; an upstream source-level patch commit is available on GNU Savannah.
Integer overflow in GNU gawk's builtin.c (versions 5.4.0 and below) enables heap metadata corruption and memory exhaustion when gawk processes attacker-crafted input. The flaw stems from a CWE-190 integer wraparound condition that can be triggered locally to overwrite heap objects with attacker-controlled bytes, potentially escalating from a denial-of-service to memory corruption with partial integrity impact. No public exploit identified at time of analysis, and CERT-PL reported this with a low CVSS 4.0 base score of 2.1, reflecting a limited, local attack surface with specific attack prerequisites.
Heap-based buffer overflow in GNU LibreDWG 0.13.4-154-g0b573035 allows a local low-privileged attacker to corrupt heap memory by supplying a crafted DWG file processed through the R2004 section decompressor, yielding partial confidentiality, integrity, and availability impact. The vulnerability resides in `decompress_R2004_section` within `src/decode.c` and is exploitable whenever LibreDWG parses attacker-controlled R2004-format DWG content. A public proof-of-concept exploit file has been disclosed on GitHub; no CISA KEV listing is present, indicating no confirmed widespread active exploitation at time of analysis.
Integer overflow in Samsung's open-source rlottie animation rendering library leads to buffer overflow, with high availability impact including potential crash or memory corruption. Exploitation requires local access, low privileges, user interaction, and high attack complexity, making this a lower-urgency finding despite the buffer overflow class. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog. The upstream fix is available as a GitHub pull request (#595), though a formally tagged patched release version has not been independently confirmed.
Out-of-bounds stack write in Zephyr's nRF70 Wi-Fi driver exposes embedded systems to memory corruption when the nRF70 co-processor returns a power-save event with more than eight TWT flow entries. The vulnerable function `nrf_wifi_event_proc_get_power_save_info()` blindly copies co-processor-supplied TWT entries into a fixed 8-element stack array without validating `num_twt_flows` against `WIFI_MAX_TWT_FLOWS`, enabling heap/stack corruption of approximately 40 bytes per excess entry. No public exploit code exists and the flaw is not listed in CISA KEV, but the adjacent-network attack vector and the indirect over-the-air influence path via a rogue AP manipulating TWT sessions make this a meaningful risk in Wi-Fi 6 (802.11ax) deployment environments running Zephyr with `CONFIG_NRF70_STA_MODE`.
Use-after-free and double-free in Zephyr RTOS's experimental USB host stack (CONFIG_USB_HOST_STACK, introduced in v4.4.0) allows an attacker with physical USB access to crash the target device or corrupt live kernel slab objects by bouncing a USB device connection to trigger a second removal event after the slab has already been freed. The flaw exists because usbh_device_disconnect() frees the root usb_device slab object without clearing the cached ctx->root pointer, and UHC controller drivers (uhc_max3421e, uhc_mcux_common) emit UHC_EVT_DEV_REMOVED directly from hardware line-state with no debounce or re-entry guard. No public exploit identified at time of analysis, and no CISA KEV listing; the physical-access prerequisite substantially constrains the realistic attacker population.
Out-of-bounds write in Zephyr RTOS's Bluetooth BAP Broadcast Assistant (subsys/bluetooth/audio/bap_broadcast_assistant.c v4.4.0 and earlier) allows a BLE-adjacent attacker operating one or more malicious Scan Delegator peripherals to corrupt the target device's memory or cause a denial of service. The root cause is a file-static 512-byte att_buf (net_buf_simple) shared across all connection instances: when the Broadcast Assistant holds two or more concurrent BLE connections, concurrent GATT notification callbacks interleave writes into this buffer without tailroom checks, enabling writes past the BSS boundary into adjacent memory. No public exploit has been identified and exploitation requires high attack complexity, but the memory corruption primitive is serious for embedded/IoT targets where crash recovery may be unavailable.
Heap-based out-of-bounds read in ImageMagick before 7.1.2-19 is triggered when processing an image carrying an unrecognized magnify:method value, causing the magnify operation to read beyond allocated heap memory. Affected systems running any version prior to 7.1.2-19 can be impacted when a user or automated pipeline processes a specially crafted image file, with outcomes ranging from partial memory disclosure to application crash. No active exploitation is confirmed (not in CISA KEV) and no public proof-of-concept has been identified at time of analysis, and the CVSS 4.0 score of 4.8 (Medium) reflects the limited local/interactive nature of the attack.
Out-of-bounds read in mtr's ipinfo_lookup() function allows a DNS-layer attacker to reliably crash the tool by serving a crafted TXT response during AS-number lookups. mtr through version 0.96 is affected; the root cause is that dn_expand() receives the total response length as its boundary argument rather than the safe, validated packet end - so a >512-byte response carrying a malicious compression pointer in the answer NAME field directs the read past the buffer. No public exploit code and no CISA KEV listing exist at time of analysis, though the crash is described as deterministic once the attacker controls the DNS response.
Heap overflow in libarchive's PAX extended header parser allows exploitation via a maliciously crafted tar archive containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation of the affected system could result in a denial of service condition or, in more serious cases, arbitrary code execution under the privileges of the process invoking libarchive. No public exploit code or active exploitation has been confirmed at time of analysis, though a GitHub pull request (#3253) indicating an upstream fix is available suggests the issue is reproducible and patch-ready. The official CVSS score of 3.9 (Low) conflicts materially with the vendor-applied RCE tag, a discrepancy that warrants independent validation.
Out-of-bounds memory write in Samsung Pass prior to version 5.2.10.3 enables local privileged attackers to corrupt process memory, producing high integrity and availability impact with limited confidentiality exposure. The root cause is improper input validation - a buffer overflow class defect - confirmed by Samsung's mobile security team and catalogued under EUVD-2026-42827. No public exploit code or CISA KEV listing has been identified; Samsung has released version 5.2.10.3 as the remediation.
Boundary validation failure in GoBGP's BGP OPEN capability parser allows a remote peer to send a malformed OPEN message that causes concrete capability decoders to read beyond the declared CapLen field, enabling attacker-controlled bytes to be interpreted as capability values - most critically, as a 4-octet AS number that influences peer AS validation and BGP session establishment decisions. Affected is GoBGP v4 (pkg:go/github.com_osrg_gobgp_v4), with the 4-octet AS capability (code 65) identified as the highest-impact case. A parser-level proof-of-concept is publicly described in GitHub Security Advisory GHSA-gjrg-jjr3-56cm; no active exploitation has been confirmed and this CVE does not appear in the CISA KEV catalog. IMPORTANT METADATA CONFLICT: The provided intelligence tags label this as 'RCE, Buffer Overflow, Information Disclosure' - all three directly contradict the CVE description, which explicitly states the issue is not arbitrary memory corruption, remote code execution, or information disclosure; security teams must disregard those tags.
Path traversal in psd-tools through v1.17.0 exposes any application processing untrusted PSD files to arbitrary file write and secondary arbitrary file read via the SmartObject API. SmartObject.save() consumes the embedded smart-object filename verbatim from the PSD binary - without basename stripping, absolute-path rejection, or directory-escape filtering - allowing a crafted PSD to write attacker-supplied bytes to any path the process can reach. A secondary issue in SmartObject.open() for external-kind objects uses the attacker-controlled fullPath descriptor as a read source, enabling file exfiltration to the write destination. A standalone proof-of-concept is publicly confirmed in the advisory; the fix is vendor-confirmed in v1.17.1 (PR #657). No public exploit identified at time of analysis beyond the advisory-embedded POC, and no CISA KEV listing was found.
Stack buffer overflow in Vim's SAL sound-folding spell engine prior to version 9.2.0725 crashes the editor by writing a null byte one position past the end of a MAXWLEN-element stack buffer in spell_soundfold_sal(). Exploitation requires a user to open Vim with a SAL-based spell file active under a non-multibyte 8-bit encoding and trigger sound-based spell suggestions on a boundary-length word, corrupting the eval_soundfold() stack frame. No public exploit has been identified at time of analysis, and the impact is limited to availability (editor crash) with no confidentiality or integrity consequences.
Memory exhaustion in Juniper Networks Junos OS and Junos OS Evolved snmpd allows an authenticated network attacker to crash SNMP monitoring by sending specific valid SNMPv3 queries that trigger an out-of-bounds write and progressive memory leak. The snmpd process will exhaust available memory over time, crash, and restart, rendering SNMP-based network monitoring unavailable for the duration of each crash cycle. No public exploit code has been identified at time of analysis, and this is not listed in CISA KEV; however, the CVSS 4.0 supplemental metric AU:Y indicates the attack is automatable.
Stack-based buffer overflow in the Mercusys MW302R (EU) V1 1.4.10 Build 231023 administrative web interface allows an authenticated attacker with administrative access on the same network segment to crash the device by sending a specially crafted HTTP request. The crash results from control flow being redirected to an arbitrary instruction address - a classic CWE-121 stack overflow pattern that produces denial of service. No public exploit is confirmed in CISA KEV, though a researcher GitHub gist (BarrYPL/13dcd071673866cbbfaaa05085b98cf3) appears to document the finding and may constitute a proof-of-concept write-up. EPSS probability is very low at 0.16% (6th percentile), consistent with a niche consumer router model.
Out-of-bounds write in the Juniper Networks Junos OS http-gatekeeper (http-gk) process on SRX Series firewalls crashes the process when handling crafted network requests, taking down all web-management-dependent services including J-Web, remote-access VPN, and firewall authentication until automatic process recovery. Exploitation is gated on a specific non-default configuration - remote-access VPN with pre-logon compliance check enabled - limiting the exposed population to SRX deployments that actively use this feature. No public exploit code and no CISA KEV listing have been identified at time of analysis, and the official CVSS 5.3 score reflects the limited, reversible availability-only impact.

No public exploit code exists and no active exploitation has been identified (EPSS: 0.31%, 22nd percentile; SSVC exploitation status: none), placing this in a lower-priority remediation tier despite its exceptionally broad product footprint.
Privilege escalation to full system control is achievable in Windows Storage Spaces Direct via a CWE-190 integer overflow that causes arithmetic wraparound, exploitable by an attacker with physical access to affected hardware. The flaw spans Windows 10 (versions 1607-22H2), Windows 11 (24H2-26H1), and Windows Server 2016 through 2025, representing a broad Microsoft platform footprint. Despite the C:H/I:H/A:H impact profile confirmed by SSVC as 'technical impact: total,' the physical access prerequisite (AV:P) is a hard constraint; SSVC additionally confirms exploitation status as none, no public exploit code exists, and EPSS sits at 0.31% (23rd percentile), making this a low operational priority for most organizations.
Buffer over-read in Fortinet FortiOS and FortiProxy exposes sensitive memory contents to authenticated network attackers across multiple product lines including FortiPAM and FortiSwitchManager. The flaw, rooted in CWE-126 (buffer over-read), allows low-privileged remote users to read beyond allocated buffer boundaries, resulting in partial information disclosure with no integrity or availability impact. No active exploitation confirmed in CISA KEV, but the CVSS temporal vector includes E:P indicating proof-of-concept exploit code exists, and an official fix is available per RL:O.
FortiOS across the 7.2, 7.4, and 7.6 release trains leaks portions of device runtime memory to authenticated remote attackers via a buffer over-read in redirect response handling. Exploitation requires valid credentials but no elevated privileges, and proof-of-concept code exists (CVSS temporal E:P). An official vendor fix is confirmed available (RL:O), though unpatched instances of FortiOS 7.2.x, 7.4.0-7.4.8, and 7.6.0-7.6.2 remain at risk of sensitive memory disclosure - a consequential exposure given that FortiOS processes session tokens, credentials, and cryptographic material at runtime.
Information disclosure in Fortinet FortiAuthenticator (6.5 all versions and 6.6.0–6.6.2) lets a remote unauthenticated attacker read out-of-bounds memory via a specially crafted request, exposing sensitive in-memory data. The CVSS temporal metrics (E:F, RC:C) indicate a functional, confirmed exploit is understood by the vendor, and an official fix is available (RL:O). No CISA KEV listing is present, so this is not confirmed as actively exploited despite the mature exploit signal.
Stack-based buffer overflow in Fortinet FortiOS, FortiPAM, FortiProxy, and FortiSASE enables arbitrary code execution for a privileged authenticated attacker capable of bypassing ASLR and stack canary protections via crafted HTTP requests. The CVSS temporal metric E:P confirms proof-of-concept exploit code exists, and RL:O confirms an official patch has been released by Fortinet (advisory FG-IR-26-148). This vulnerability is not listed in CISA KEV at time of analysis, and the dual prerequisites of privileged access plus memory-protection bypass substantially constrain real-world exploitability despite the critical CIA impact triad.
Denial-of-service in Rockwell Automation CompactLogix/GuardLogix 5380, CompactLogix 5480, and ControlLogix/GuardLogix 5580 controllers running boot firmware below version 1.072 lets a remote unauthenticated attacker write malformed file data that forces the device into a major non-recoverable fault (MNRF), halting the controlled process until manual recovery. The flaw carries a CVSS 4.0 base of 9.2 driven purely by availability impact (no data confidentiality or integrity loss) and requires no authentication or user interaction. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial-of-service in Rockwell Automation Logix programmable controllers allows a remote unauthenticated attacker to write invalid file data that forces the device into a Major Non-Recoverable Fault (MNRF), halting the industrial process it controls. Rated CVSS 4.0 9.2 (Critical) with availability as the sole impact, the flaw is a CWE-120 buffer overflow reachable over the network with no privileges or user interaction. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, but the low attack complexity makes it a high-priority patch for OT environments.
Remote denial-of-service in Rockwell Automation CompactLogix 5370, Compact GuardLogix 5370, ControlLogix 5570, and GuardLogix 5570 controllers allows a remote user to push a malformed project file that forces the controller into a Major Non-Recoverable Fault (MNRF), halting the controlled process until manual recovery. The CVSS 4.0 score of 9.2 reflects high availability impact on both the controller and the downstream physical process (VA:H/SA:H) with no authentication or user interaction required per the vendor vector. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV, but the loss of a safety-rated (GuardLogix) controller makes availability the dominant concern.
Out-of-bounds read in Citrix Secure Access Client for Windows (all versions before 26.6.1.20) enables a local low-privileged attacker to read memory beyond an allocated buffer boundary, resulting in high confidentiality impact with no integrity or availability consequence. The CVSS 4.0 score of 6.8 reflects the local attack vector and low-privilege requirement, meaning an attacker must already hold a foothold on the endpoint. No public exploit code and no active exploitation (CISA KEV) have been identified at time of analysis.
Out-of-bounds read in libsoup 3.6.6 exposes WebSocket clients to memory disclosure and crashes when connecting to malicious servers. The incomplete fix for CVE-2026-0716 (commit 6ff7ef0) placed the integer overflow guard exclusively inside the masked-frame branch, leaving the unmasked server-to-client frame path entirely unprotected - allowing a crafted payload length near UINT64_MAX to bypass the guard entirely. No public exploit code or active exploitation (CISA KEV) has been identified, but the CVSS AC:H rating reflects the non-trivial preconditions: a specific client configuration and attacker-controlled server are both required.
Buffer overflow in SUSE Virtual Machine Driver Pack allows a local attacker with registry modification rights to corrupt driver integrity. Affected are all versions of the pack before upstream commit e7a602ec232756ead019bdf19d6d3b9d010cc94b, targeting virtualized guest environments running SUSE's paravirtual drivers. No public exploit exists and the vendor explicitly states no feasible exploitation path is currently known; no public exploit identified at time of analysis.
Out-of-bounds read and write conditions exist in the `wrap_lines_measure` function, as tracked under GHSA-pjjp-65r7-ppgm and reported by Ubuntu. Memory corruption of this class - simultaneous OOB read and write - typically enables attackers to leak sensitive memory contents and corrupt heap or stack state, potentially leading to arbitrary code execution or process crash depending on exploitability conditions. No CVSS vector, EPSS score, KEV status, or POC availability data was supplied, so severity and real-world risk cannot be quantified with confidence at this time.
Out-of-bounds bit clear operations in a Matroska container format parser allow processing of maliciously crafted media files containing negative ReadOrder field values to corrupt memory. The vulnerability arises when a negative integer ReadOrder value is used without adequate sign checking, causing bit-clear write operations to target memory locations outside the intended buffer boundary. Affected deployments include software in the Ubuntu ecosystem that parses Matroska (.mkv/.webm) files; no public exploit has been identified at time of analysis and CISA KEV status is not confirmed.
Out-of-bounds read in Blender 3.0.0 through 5.1.2 allows an attacker to crash the application or disclose heap memory contents by convincing a user to open a specially crafted .blend file containing a malicious member_index value in the SDNA block. The vulnerability stems from missing bounds validation on a signed short index used directly as an array subscript in sdna_expand_names(), enabling both denial-of-service via SIGSEGV and limited heap memory disclosure. No public exploit code or active exploitation has been identified at time of analysis, but the file-based attack vector makes social engineering a realistic delivery mechanism.
Stack-based buffer overflow in gawk's readdir extension (extension/readdir.c, ftype() routine) affects all gawk releases through version 5.4.0, enabling a local attacker to crash the process and theoretically achieve code execution. The RCE angle is explicitly unconfirmed by the reporter (CERT-PL), making denial-of-service the primary demonstrated impact at this time. No public exploit identified at time of analysis; an upstream source-level patch commit is available on GNU Savannah.
Integer overflow in GNU gawk's builtin.c (versions 5.4.0 and below) enables heap metadata corruption and memory exhaustion when gawk processes attacker-crafted input. The flaw stems from a CWE-190 integer wraparound condition that can be triggered locally to overwrite heap objects with attacker-controlled bytes, potentially escalating from a denial-of-service to memory corruption with partial integrity impact. No public exploit identified at time of analysis, and CERT-PL reported this with a low CVSS 4.0 base score of 2.1, reflecting a limited, local attack surface with specific attack prerequisites.
Heap-based buffer overflow in GNU LibreDWG 0.13.4-154-g0b573035 allows a local low-privileged attacker to corrupt heap memory by supplying a crafted DWG file processed through the R2004 section decompressor, yielding partial confidentiality, integrity, and availability impact. The vulnerability resides in `decompress_R2004_section` within `src/decode.c` and is exploitable whenever LibreDWG parses attacker-controlled R2004-format DWG content. A public proof-of-concept exploit file has been disclosed on GitHub; no CISA KEV listing is present, indicating no confirmed widespread active exploitation at time of analysis.
Integer overflow in Samsung's open-source rlottie animation rendering library leads to buffer overflow, with high availability impact including potential crash or memory corruption. Exploitation requires local access, low privileges, user interaction, and high attack complexity, making this a lower-urgency finding despite the buffer overflow class. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog. The upstream fix is available as a GitHub pull request (#595), though a formally tagged patched release version has not been independently confirmed.
Out-of-bounds stack write in Zephyr's nRF70 Wi-Fi driver exposes embedded systems to memory corruption when the nRF70 co-processor returns a power-save event with more than eight TWT flow entries. The vulnerable function `nrf_wifi_event_proc_get_power_save_info()` blindly copies co-processor-supplied TWT entries into a fixed 8-element stack array without validating `num_twt_flows` against `WIFI_MAX_TWT_FLOWS`, enabling heap/stack corruption of approximately 40 bytes per excess entry. No public exploit code exists and the flaw is not listed in CISA KEV, but the adjacent-network attack vector and the indirect over-the-air influence path via a rogue AP manipulating TWT sessions make this a meaningful risk in Wi-Fi 6 (802.11ax) deployment environments running Zephyr with `CONFIG_NRF70_STA_MODE`.
Use-after-free and double-free in Zephyr RTOS's experimental USB host stack (CONFIG_USB_HOST_STACK, introduced in v4.4.0) allows an attacker with physical USB access to crash the target device or corrupt live kernel slab objects by bouncing a USB device connection to trigger a second removal event after the slab has already been freed. The flaw exists because usbh_device_disconnect() frees the root usb_device slab object without clearing the cached ctx->root pointer, and UHC controller drivers (uhc_max3421e, uhc_mcux_common) emit UHC_EVT_DEV_REMOVED directly from hardware line-state with no debounce or re-entry guard. No public exploit identified at time of analysis, and no CISA KEV listing; the physical-access prerequisite substantially constrains the realistic attacker population.
Out-of-bounds write in Zephyr RTOS's Bluetooth BAP Broadcast Assistant (subsys/bluetooth/audio/bap_broadcast_assistant.c v4.4.0 and earlier) allows a BLE-adjacent attacker operating one or more malicious Scan Delegator peripherals to corrupt the target device's memory or cause a denial of service. The root cause is a file-static 512-byte att_buf (net_buf_simple) shared across all connection instances: when the Broadcast Assistant holds two or more concurrent BLE connections, concurrent GATT notification callbacks interleave writes into this buffer without tailroom checks, enabling writes past the BSS boundary into adjacent memory. No public exploit has been identified and exploitation requires high attack complexity, but the memory corruption primitive is serious for embedded/IoT targets where crash recovery may be unavailable.
Heap-based out-of-bounds read in ImageMagick before 7.1.2-19 is triggered when processing an image carrying an unrecognized magnify:method value, causing the magnify operation to read beyond allocated heap memory. Affected systems running any version prior to 7.1.2-19 can be impacted when a user or automated pipeline processes a specially crafted image file, with outcomes ranging from partial memory disclosure to application crash. No active exploitation is confirmed (not in CISA KEV) and no public proof-of-concept has been identified at time of analysis, and the CVSS 4.0 score of 4.8 (Medium) reflects the limited local/interactive nature of the attack.
Out-of-bounds read in mtr's ipinfo_lookup() function allows a DNS-layer attacker to reliably crash the tool by serving a crafted TXT response during AS-number lookups. mtr through version 0.96 is affected; the root cause is that dn_expand() receives the total response length as its boundary argument rather than the safe, validated packet end - so a >512-byte response carrying a malicious compression pointer in the answer NAME field directs the read past the buffer. No public exploit code and no CISA KEV listing exist at time of analysis, though the crash is described as deterministic once the attacker controls the DNS response.
Heap overflow in libarchive's PAX extended header parser allows exploitation via a maliciously crafted tar archive containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation of the affected system could result in a denial of service condition or, in more serious cases, arbitrary code execution under the privileges of the process invoking libarchive. No public exploit code or active exploitation has been confirmed at time of analysis, though a GitHub pull request (#3253) indicating an upstream fix is available suggests the issue is reproducible and patch-ready. The official CVSS score of 3.9 (Low) conflicts materially with the vendor-applied RCE tag, a discrepancy that warrants independent validation.
Out-of-bounds memory write in Samsung Pass prior to version 5.2.10.3 enables local privileged attackers to corrupt process memory, producing high integrity and availability impact with limited confidentiality exposure. The root cause is improper input validation - a buffer overflow class defect - confirmed by Samsung's mobile security team and catalogued under EUVD-2026-42827. No public exploit code or CISA KEV listing has been identified; Samsung has released version 5.2.10.3 as the remediation.
Boundary validation failure in GoBGP's BGP OPEN capability parser allows a remote peer to send a malformed OPEN message that causes concrete capability decoders to read beyond the declared CapLen field, enabling attacker-controlled bytes to be interpreted as capability values - most critically, as a 4-octet AS number that influences peer AS validation and BGP session establishment decisions. Affected is GoBGP v4 (pkg:go/github.com_osrg_gobgp_v4), with the 4-octet AS capability (code 65) identified as the highest-impact case. A parser-level proof-of-concept is publicly described in GitHub Security Advisory GHSA-gjrg-jjr3-56cm; no active exploitation has been confirmed and this CVE does not appear in the CISA KEV catalog. IMPORTANT METADATA CONFLICT: The provided intelligence tags label this as 'RCE, Buffer Overflow, Information Disclosure' - all three directly contradict the CVE description, which explicitly states the issue is not arbitrary memory corruption, remote code execution, or information disclosure; security teams must disregard those tags.
Path traversal in psd-tools through v1.17.0 exposes any application processing untrusted PSD files to arbitrary file write and secondary arbitrary file read via the SmartObject API. SmartObject.save() consumes the embedded smart-object filename verbatim from the PSD binary - without basename stripping, absolute-path rejection, or directory-escape filtering - allowing a crafted PSD to write attacker-supplied bytes to any path the process can reach. A secondary issue in SmartObject.open() for external-kind objects uses the attacker-controlled fullPath descriptor as a read source, enabling file exfiltration to the write destination. A standalone proof-of-concept is publicly confirmed in the advisory; the fix is vendor-confirmed in v1.17.1 (PR #657). No public exploit identified at time of analysis beyond the advisory-embedded POC, and no CISA KEV listing was found.
Stack buffer overflow in Vim's SAL sound-folding spell engine prior to version 9.2.0725 crashes the editor by writing a null byte one position past the end of a MAXWLEN-element stack buffer in spell_soundfold_sal(). Exploitation requires a user to open Vim with a SAL-based spell file active under a non-multibyte 8-bit encoding and trigger sound-based spell suggestions on a boundary-length word, corrupting the eval_soundfold() stack frame. No public exploit has been identified at time of analysis, and the impact is limited to availability (editor crash) with no confidentiality or integrity consequences.
Memory exhaustion in Juniper Networks Junos OS and Junos OS Evolved snmpd allows an authenticated network attacker to crash SNMP monitoring by sending specific valid SNMPv3 queries that trigger an out-of-bounds write and progressive memory leak. The snmpd process will exhaust available memory over time, crash, and restart, rendering SNMP-based network monitoring unavailable for the duration of each crash cycle. No public exploit code has been identified at time of analysis, and this is not listed in CISA KEV; however, the CVSS 4.0 supplemental metric AU:Y indicates the attack is automatable.
Stack-based buffer overflow in the Mercusys MW302R (EU) V1 1.4.10 Build 231023 administrative web interface allows an authenticated attacker with administrative access on the same network segment to crash the device by sending a specially crafted HTTP request. The crash results from control flow being redirected to an arbitrary instruction address - a classic CWE-121 stack overflow pattern that produces denial of service. No public exploit is confirmed in CISA KEV, though a researcher GitHub gist (BarrYPL/13dcd071673866cbbfaaa05085b98cf3) appears to document the finding and may constitute a proof-of-concept write-up. EPSS probability is very low at 0.16% (6th percentile), consistent with a niche consumer router model.
Out-of-bounds write in the Juniper Networks Junos OS http-gatekeeper (http-gk) process on SRX Series firewalls crashes the process when handling crafted network requests, taking down all web-management-dependent services including J-Web, remote-access VPN, and firewall authentication until automatic process recovery. Exploitation is gated on a specific non-default configuration - remote-access VPN with pre-logon compliance check enabled - limiting the exposed population to SRX deployments that actively use this feature. No public exploit code and no CISA KEV listing have been identified at time of analysis, and the official CVSS 5.3 score reflects the limited, reversible availability-only impact.
Use-after-free in Open5GS 2.7.7's AMF component allows a local low-privileged user to access freed memory within the `amf_context_final` function in `src/amf/context.c`, producing a low-severity confidentiality exposure. Exploitation is strictly local - no network vector exists - and a public proof-of-concept is confirmed by the CVSS 4.0 E:P supplemental modifier. This vulnerability is not listed in the CISA KEV catalog and carries a CVSS 4.0 base score of 1.9, reflecting its constrained real-world impact on what is a niche, telecom-research-oriented software stack.
Heap buffer overflow in pymonocypher's argon2i_32 function allows memory corruption when callers supply an undersized nb_blocks buffer, violating the library's API contract without triggering any bounds check. Applications using pymonocypher prior to version 4.0.2.8 that invoke the Argon2i password-hashing interface are at risk of heap corruption, which can produce crashes or potentially enable controlled memory writes. No public exploit code has been identified at time of analysis, and no active exploitation has been confirmed.
Stack buffer overflow in Vinchin Backup & Recovery through 9.0.0.86562 exposes the agentlink_server service to unauthenticated remote exploitation via the ModuleHandShake function. An attacker supplying an oversized _listen_uuid value triggers unsafe strcpy() into a fixed-length stack buffer, overwriting the saved return address and enabling process crash or control flow hijack. No public exploit or active exploitation has been confirmed at time of analysis, though the CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N) confirms the attack is network-reachable without authentication or user interaction.
Heap buffer overflow in Vinchin Backup & Recovery through version 9.0.0.86562 allows unauthenticated remote attackers to crash the agentlink_server process or corrupt heap memory without any prior access or user interaction. The agentlink_server service accepts a TCP packet body_len field without bounds validation, passing the attacker-controlled value directly to recv() and enabling heap writes of up to approximately 4 GiB beyond the allocated buffer. This vulnerability is not listed in CISA KEV and no public exploit code is confirmed at time of analysis, though the heap overflow magnitude raises concern for potential code execution beyond simple denial-of-service.
Out-of-bounds read in GPAC MP4Box version 26.03-DEV allows local low-privileged attackers to cause a low-severity availability impact by supplying a crafted input that manipulates the `num_langs` argument in the `vobsub_read_idx` function of `vobsub.c`. A proof-of-concept exploit has been publicly disclosed via GitHub issue #3611 and the CVSS 4.0 E:P modifier confirms its availability. Two upstream commits have been applied to address the flaw, though no standalone patched release version has been independently confirmed.
Heap-based buffer overflow in GNU LibreDWG up to version 0.13.4 allows local low-privileged attackers to corrupt heap memory via a specially crafted DWG file containing malicious BMP image data processed by the dwg_bmp function in src/dwg.c. A public proof-of-concept exploit (a crafted R13/R2000 .dwg file) has been disclosed on GitHub, raising the urgency for affected deployments that process untrusted DWG input. No confirmed active exploitation (CISA KEV) has been recorded, and a vendor-released patch in version 0.14 fully resolves the issue.
Out-of-bounds read and reachable assertion vulnerabilities in Samsung's open-source Escargot JavaScript engine allow a local attacker to cause a denial of service and limited data manipulation by supplying crafted JavaScript input. All versions prior to commit 2dee22f5c7b8bf31cb7252d7731fae8c07f2842c are affected, with the primary real-world impact being an availability loss (crash) and low-confidence integrity effect. No public exploit code or CISA KEV listing has been identified at time of analysis.
Heap-based buffer overflow in Samsung's open-source Escargot JavaScript engine corrupts heap memory when processing maliciously crafted input, leading to a high-severity availability impact and a limited integrity impact. The vulnerability affects all Escargot releases before commit ef525f337fafddecde77a3c426212a84bb20cb98, targeting embedded and IoT contexts where the engine is deployed - most notably Samsung TV appliances. No public exploit identified at time of analysis, and no CISA KEV listing, but the local-vector, low-complexity nature of heap overflows makes this reliably triggerable once an attacker can supply crafted input to the engine.
Out-of-bounds read and write vulnerabilities in Samsung's open-source Escargot JavaScript engine allow a local attacker to cause memory corruption leading to high availability impact and limited integrity compromise. All Escargot versions prior to commit 779f6bedf58f334dec64b0a51ebb724b4708b84a are affected, with the engine's primary deployment in Samsung TV appliance and IoT platforms. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in CISA KEV; however, the CVSS-assigned high availability impact and the buffer overflow primitive make crash-based denial-of-service the primary realistic threat.
Stack-based buffer overflow in Samsung's Escargot JavaScript engine enables local attackers to crash the engine or corrupt stack memory by supplying malicious JavaScript input, requiring user interaction to trigger. All Escargot releases prior to commit b30b63fc63b403907d8137da1c65aaa4521fe74e are affected, with impacts including high availability loss and limited integrity compromise. No public exploit identified at time of analysis and this vulnerability has not been added to CISA KEV, though the local-vector, user-interaction requirement meaningfully constrains real-world exploitation surface.
Integer overflow in the virtio-gpu driver's 2D image allocation path of the Linux kernel exposes virtualized guest systems to potential heap corruption. The flaw resides in an insufficient overflow check performed before allocating memory for a 2D image resource in the virtio-gpu paravirtualized GPU subsystem. An attacker or malicious process with access to GPU resource creation within an affected guest OS could trigger the overflow, potentially leading to out-of-bounds memory writes and kernel-level memory corruption. No public exploit or KEV listing is identified at time of analysis.

No impact, attack vector, or affected component can be determined from the provided data. Security teams should treat this as an unresolved entry requiring direct vendor advisory lookup before any risk decision is made.
Integer overflow in Google Chrome's Extensions API (versions prior to 150.0.7871.115) enables an out-of-bounds memory read, leaking limited browser memory content to a crafted malicious extension. Exploitation requires convincing a user to install the attacker-controlled extension, constraining this to social engineering or supply chain scenarios rather than opportunistic mass exploitation. No public exploit has been identified and EPSS sits at 0.10% (1st percentile), making real-world exploitation probability very low despite Chromium's internal 'High' severity designation.
Denial of service in Wireshark 4.6.0-4.6.6 and 4.4.0-4.4.16 is caused by a heap-based buffer overflow in the Catapult DCT2000 protocol dissector, crashing the application when a crafted capture file is opened. The CVSS local attack vector (AV:L) and required user interaction (UI:R) constrain exploitation to scenarios where an analyst is socially engineered into opening a malicious capture file - no remote or unauthenticated network exploitation path exists. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV; vendor-released fixes are available in 4.6.7 and 4.4.17.
The pcapng file parser in Wireshark 4.6.0 through 4.6.6 contains a heap-based buffer overflow (CWE-122) that crashes the application, resulting in denial of service. An attacker must convince a user to open a specially crafted pcapng capture file, making this a social-engineering-dependent attack with no network-facing exploitation path. No public exploit code has been identified at time of analysis and the vulnerability is not listed in CISA KEV; a vendor patch is available in Wireshark 4.6.7.
Heap-based buffer overflow in Wireshark's Z39.50 protocol dissector crashes the application when processing malformed Z39.50 PDUs, resulting in denial of service. Affected versions span the 4.4.x branch (4.4.0-4.4.16) and 4.6.x branch (4.6.0-4.6.6). An attacker can trigger the crash by persuading an analyst to open a crafted packet capture file or by injecting malicious Z39.50 traffic onto a monitored network segment; no active exploitation (CISA KEV) or public exploit code has been identified at time of analysis.
Denial of service in Wireshark's DBS Etherwatch dissector affects release branches 4.6.0 through 4.6.6 and 4.4.0 through 4.4.16, where a malformed capture file or crafted packet can crash the application. The flaw is a stack-based buffer overflow (CWE-121) that manifests only as an availability impact - no confidentiality or integrity loss and no confirmed code execution - carrying a 7.5 (High) CVSS. No public exploit identified at time of analysis and the CVE is not listed in CISA KEV.
Stack-based buffer overflow in Wireshark's IEEE 802.11 (Wi-Fi) protocol dissector crashes the application, resulting in denial of service across versions 4.6.0-4.6.6 and 4.4.0-4.4.16. An attacker with the ability to deliver a malicious packet capture file, or inject crafted 802.11 frames into a live capture session, can crash the Wireshark process on a victim analyst's machine. No public exploit code has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog; vendor-released patches (4.6.7 and 4.4.17) are available.
Denial of service in Wireshark 4.6.0 through 4.6.6 lets a remote attacker crash the application by feeding it a malformed TLS packet using the Encrypted Client Hello (ECH) extension, triggering a heap buffer overflow in the ECH decryptor. No authentication or user interaction beyond processing the traffic is required, though impact is limited to availability (analyzer crash) with no code execution or data disclosure claimed. Publicly available exploit code exists per SSVC (POC), EPSS is low at 0.14% (4th percentile), and it is not listed in CISA KEV.
Denial of service in Wireshark's ciscodump remote capture utility (extcap) affects versions 4.6.0 through 4.6.6 and 4.4.0 through 4.4.16, where a heap-based buffer overflow (CWE-122) can crash the capture tool. An attacker able to feed crafted data to a running ciscodump session can terminate the process, disrupting live packet capture. A POC is referenced by CISA's SSVC assessment (no public exploit code independently identified), it is not in CISA KEV, and EPSS is very low at 0.10% (1st percentile), indicating minimal likelihood of widespread exploitation.
Out-of-bounds read in U-Boot's TCP stack (net/tcp.c, tcp_rx_state_machine()) allows remote unauthenticated attackers to corrupt bootloader TCP connection state by sending a crafted packet with deliberately mismatched IP total length and TCP data offset fields. Affected builds span U-Boot through 2026.04-rc3, but only when compiled with CONFIG_PROT_TCP - a non-default option. Impact is disruption of TCP window calculations via corruption of rmt_win_scale and rmt_timestamp variables, potentially breaking network-based boot sequences. No public exploit has been identified at time of analysis, and this vulnerability is not currently listed in CISA KEV.
Heap buffer overflow in ImageMagick's FTXT encoder exposes systems to denial of service and potential information disclosure when processing attacker-crafted image files. All ImageMagick versions before 7.1.2-19 are affected due to missing boundary checks when parsing the ftxt:format parameter, allowing an out-of-bounds read (CWE-125) in the FTXT encoder component. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog, though a vendor patch is available at 7.1.2-19.
Heap-buffer-overflow read in ImageMagick's GetPixelIndex function exposes limited heap memory contents and can cause partial availability impact in affected 6.x and 7.x branches before the patched releases. The root cause is a metadata-allocation race in OpenPixelCache, which updates image channel metadata before confirming successful pixel cache memory allocation, leaving GetPixelIndex to operate on stale channel counts. Exploitation requires high privilege access and the ability to induce memory or disk allocation failures, yielding only limited confidentiality and availability impact; no public exploit code and no CISA KEV listing are associated with this CVE.
Out-of-bounds read in Foxit PDF Editor and Foxit PDF Reader allows a local attacker to crash the application and potentially expose adjacent memory contents by delivering a specially crafted PDF containing malicious JavaScript. The JavaScript manipulates page and document objects to desynchronize internal page-related state from the renderer's trusted page count; when the renderer subsequently accesses page objects using the stale index, it reads beyond valid memory bounds. No public exploit identified at time of analysis and no CISA KEV listing, but the broad affected version ranges across multiple major release branches (13.x, 14.x, and 2026.x) means a large proportion of unpatched Foxit deployments are exposed.
Foxit PDF Reader and PDF Editor crash with potential memory disclosure when processing maliciously crafted PDF documents containing JavaScript that causes reentrancy during page opening or form formatting. The reentrancy leaves the document object in an inconsistent state; when the application subsequently attempts to dereference stale page metadata, it reads from an invalid memory address (CWE-125 out-of-bounds read), resulting in application termination and limited memory content exposure. No public exploit code or active exploitation has been identified at time of analysis; exploitation requires a local user interaction to open a crafted PDF file.
Out-of-bounds read in Foxit PDF Reader and PDF Editor allows a local attacker to crash the application and potentially disclose limited memory contents by delivering a specially crafted PDF containing a malformed image object. The vulnerability triggers when the renderer encounters an abnormal image object, causes it to enter an incorrect processing branch, and subsequently dereferences an invalid buffer pointer during scan line conversion. No public exploit code has been identified and no CISA KEV listing exists, but the CVSS availability impact is rated High, meaning successful exploitation reliably causes application termination.
Out-of-bounds read in Foxit PDF Editor and Foxit PDF Reader crashes the application and exposes limited memory contents when a victim opens a specially crafted PDF embedding a semantically malformed color space function. Affected versions span multiple branches across both Editor and Reader products, confirmed through EUVD-2026-42198. No public exploit code or active exploitation has been identified at time of analysis; however, the low attack complexity and file-based delivery mechanism make this a plausible phishing lure in targeted campaigns against organizations relying on Foxit products.
Out-of-bounds read in Foxit PDF Editor and PDF Reader during PRC (Product Representation Compact) 3D content parsing crashes the application and leaks limited memory content. Affects multiple concurrent release trains including versions 2026.1.1, 14.0.4, and 13.2.4 and earlier. Exploitation requires a victim to open a specially crafted PDF containing a malicious PRC entity - no public exploit has been identified at time of analysis.
