The vulnerability affects kernel versions 6.16-rc1 through rc3 and potentially earlier versions; vendor-released patches are available across affected stable branches.

Denial of service in Linux kernel net/sched subsystem allows local authenticated attackers to trigger a kernel panic (BUG_ON) by manipulating HTB qdisc (hierarchical token bucket queue discipline) configuration with nested qdisc classes, causing htb_lookup_leaf to encounter an empty rbtree. The vulnerability requires low privilege and local access; no special user interaction is needed once a malicious qdisc configuration is set up. Vendor-released patches are available across multiple stable kernel series.

Linux kernel uprobes implementation allows local privileged users to cause denial of service by placing probes at invalid instruction boundaries, exploiting variable-length instruction decoding and mixing of data in text segments on architectures like ARM64. The vulnerability requires CAP_SYS_ADMIN capability, limiting exposure to privileged local attackers. Patch available across multiple stable kernel branches (6.16-rc1 through rc4 and earlier versions).

Integer wraparound in Linux kernel netlink socket receive buffer accounting allows local authenticated attackers to exhaust kernel memory by bypassing receive buffer limits via integer overflow in sk_rmem_alloc comparison. An attacker with local access can set SO_RCVBUFFORCE to INT_MAX, causing the receive buffer check to always evaluate false and permitting unlimited socket buffer allocation until out-of-memory conditions occur. CVSS 5.5 indicates local denial of service with potential system-wide impact; no active exploitation confirmed but vulnerability affects all Linux distributions.

Denial of service in Linux kernel traffic control (qdisc) subsystem allows local authenticated attackers to crash the system by creating or modifying queue disciplines with invalid parent class references. When certain qdiscs (fq, hhf, choke, etc.) invoke qdisc_tree_reduce_backlog during initialization with a null parent class, they trigger an unhandled null pointer dereference. No active exploitation confirmed (KEV not listed), but CVSS 5.5 reflects local privilege requirement with high availability impact.

A general protection fault (GPF) in the Linux kernel's md-bitmap module affects the bitmap_get_stats() function when reading bitmap statistics for RAID devices with external bitmaps. Local users with sufficient privileges can trigger a kernel panic by accessing bitmap statistics through the /proc interface, causing denial of service. The vulnerability stems from incomplete validation of bitmap storage configuration introduced by a prior fix that failed to properly check superblock validity for both internal and external bitmap modes.

Linux kernel DRM scheduler fails to signal scheduled fences when killing job entities, causing dependent applications to hang indefinitely waiting for unresolved dependencies. Authenticated local users can trigger this denial of service by terminating applications whose job dependencies are not properly cleared during entity kill operations. The vulnerability affects multiple Linux kernel versions and has been patched upstream.

Denial of service in Linux kernel nfsd (NFS server daemon) allows local authenticated attackers to crash the system by triggering undefined behavior in nfsd4_spo_must_allow() when non-v4 compound RPC requests are processed. The vulnerability stems from missing validation that incoming RPC procedures are NFSv4 COMPOUND requests before examining internal state structures, causing memory access violations and system unavailability.

Linux kernel RAS (Reliability, Availability, Serviceability) header validation in the AMD GPU driver (amdgpu) lacks input sanitization, allowing a local authenticated attacker to trigger denial of service through excessive memory allocation when reading corrupted EEPROM data. The vulnerability affects all Linux kernel versions with the vulnerable amdgpu driver code path and requires local access with standard user privileges. No public exploit code has been identified; the EPSS score of 0.02% (5th percentile) indicates low real-world exploitation probability despite the moderate CVSS 5.5 rating.

Out-of-bounds shift in the Linux kernel Squashfs filesystem allows a local attacker to trigger memory corruption by racing a LOOP_SET_BLOCK_SIZE ioctl against a concurrent Squashfs mount on the same loop device, causing sb_min_blocksize() to return 0 and the code in squashfs_fill_super() to compute a shift exponent of 64. The affected subsystem is the kernel Squashfs driver (fs/squashfs/block.c) on Linux and downstream distributions such as Debian 11. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.

A null pointer dereference vulnerability exists in the Linux kernel's interrupt simulation (genirq/irq_sim) subsystem where uninitialized pointers in the work context can be dereferenced, leading to kernel denial of service. The vulnerability affects Linux kernel versions including 6.16-rc1 and 6.16-rc2, and potentially earlier stable releases. A local attacker with unprivileged user privileges can trigger a kernel crash by invoking interrupt simulation functionality, causing system unavailability. Patches are available from the Linux kernel stable repositories, and exploitation probability is low (EPSS 0.02%, percentile 6%) despite the moderate CVSS score of 5.5.

Linux kernel NFS subsystem fails to clean up /proc/net/rpc/nfs directory when nfs_fs_proc_net_init() encounters a memory allocation failure, causing a warning when rpc_proc_exit() later attempts to remove the non-empty parent directory. The vulnerability affects kernel versions 6.16-rc1 through 6.16-rc3 and likely earlier versions, and requires local privileges to trigger via fault injection or memory pressure. While marked as availability impact (DoS via kernel warning), the practical severity is limited as it primarily causes a procfs resource leak rather than direct system compromise.

Race condition in Linux kernel NFSv4/pNFS layout draining allows local authenticated users to trigger denial of service through system hangs in writeback operations. The vulnerability exists in pnfs_update_layout() where a waiter on the NFS_LAYOUT_DRAIN bit can race with the waker when plh_outstanding count reaches zero, causing threads to block indefinitely on page locks. Patch available from upstream kernel stable branches.

Null pointer dereference in Linux kernel maple_tree memory allocator causes denial of service when the MA_STATE_PREALLOC flag is incorrectly managed during node allocation requests. Local authenticated attackers can trigger this via memory operations that request large numbers of nodes, such as VMA merges during mmap_region() calls, leading to WARN_ON() messages followed by kernel crash. Affects Linux kernel versions including 6.16 release candidates and is confirmed patched in stable branches.

A null pointer dereference vulnerability exists in the AMD display driver within the Linux kernel, where the dce_hwseq structure is accessed without proper null checking in the dce110_blank_stream function. The vulnerability affects Linux kernel versions up to 6.16-rc2 and could allow a local attacker with low privileges to cause a system crash or potentially execute arbitrary code with kernel privileges. With an EPSS score of only 0.02% and no known active exploitation, this represents a low real-world risk despite the high CVSS score.

EPSS data not provided; no public exploit identified at time of analysis, though Mozilla notes evidence of memory corruption suggesting exploitability with effort.

Null pointer dereference in Firefox and Thunderbird JavaScript engines allows remote attackers to cause denial of service via malformed closed generator objects. The vulnerability affects Firefox versions below 141, Firefox ESR versions below 115.26/128.13/140.1, Thunderbird versions below 141/128.13/140.1, and is triggered when a user visits a malicious webpage or opens a crafted email containing JavaScript that improperly resumes a closed generator. While the CVSS score is 6.5 (medium-high), the impact is limited to availability-no information disclosure or code execution is possible.

Content Security Policy bypass in Mozilla Firefox and Thunderbird allows remote attackers to circumvent CSP protections via maliciously crafted XSLT documents. The flaw affects Firefox versions prior to 141 and Firefox ESR prior to 128.13/140.1, as well as Thunderbird versions prior to 141 and Thunderbird ESR prior to 128.13/140.1. Attack requires user interaction (visiting a malicious site or opening a malicious email) but no authentication. With CVSS 8.1 (High severity) and documented in six separate Mozilla security advisories, this CSP bypass enables high-impact confidentiality and integrity violations, though no public exploit or active exploitation has been identified at time of analysis.

HTTP Basic Authentication credentials leak in Mozilla Firefox and Thunderbird via Content Security Policy (CSP) violation reports affects all versions prior to Firefox 141, Firefox ESR 128.13/140.1, and Thunderbird 141/128.13/140.1. When CSP violations occur on pages using HTTP Basic Auth, the browser incorrectly includes username:password in the violation report URL sent to the CSP report endpoint, exposing credentials to potentially untrusted third parties. With CVSS 9.8 and network-based unauthenticated attack vector (AV:N/AC:L/PR:N), this represents a critical credential disclosure vulnerability, though no public exploit or active exploitation (non-KEV) is confirmed at time of analysis.

Firefox and Thunderbird's 'Copy as cURL' feature improperly escapes shell metacharacters, allowing remote attackers to trick users into executing arbitrary commands when pasting copied network requests into a terminal. Affects Firefox <141, Firefox ESR <128.13/140.1, and Thunderbird <141, <128.13/140.1. Vendor-released patches available across all affected branches. CVSS 8.1 with network attack vector requiring user interaction; no public exploit identified at time of analysis.

In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* pgsql and pdo_pgsql escaping functions do not check if the underlying quoting functions returned errors. This could cause crashes if Postgres server rejects the string as invalid.

In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* before 8.4.10 when parsing XML data in SOAP extensions, overly large (>2Gb) XML namespace prefix may lead to null pointer dereference. This may lead to crashes and affect the availability of the target server.

CVE-2025-24294 is a Denial of Service vulnerability in DNS packet parsing libraries (specifically the resolv library) caused by insufficient validation of decompressed domain name lengths. An attacker can send a crafted DNS packet with a highly compressed domain name that, when decompressed, consumes excessive CPU resources without limit, causing the parsing thread to become unresponsive. The vulnerability affects any application using the vulnerable resolv library and has a CVSS score of 7.5 (high severity); real-world exploitation probability and active exploitation status cannot be confirmed without EPSS score and KEV data.

GNU Tar through 1.35 allows file overwrite via directory traversal in crafted TAR archives, with a certain two-step process. First, the victim must extract an archive that contains a ../ symlink to a critical directory. Second, the victim must extract an archive that contains a critical file, specified via a relative pathname that begins with the symlink name and ends with that critical file's name. Here, the extraction follows the symlink and overwrites the critical file. This bypasses the protection mechanism of "Member name contains '..'" that would occur for a single TAR archive that attempted to specify the critical file via a ../ approach. For example, the first archive can contain "x -> ../../../../../home/victim/.ssh" and the second archive can contain x/authorized_keys. This can affect server applications that automatically extract any number of user-supplied TAR archives, and were relying on the blocking of traversal. This can also affect software installation processes in which "tar xf" is run more than once (e.g., when installing a package can automatically install two dependencies that are set up as untrusted tarballs instead of official packages). NOTE: the official GNU Tar manual has an otherwise-empty directory for each "tar xf" in its Security Rules of Thumb; however, third-party advice leads users to run "tar xf" more than once into the same directory.

Uncontrolled Recursion vulnerability in Apache Commons Lang. This issue affects Apache Commons Lang: Starting with commons-lang:commons-lang 2.0 to 2.6, and, from org.apache.commons:commons-lang3 3.0 before 3.18.0. The methods ClassUtils.getClass(...) can throw StackOverflowError on very long inputs. Because an Error is usually not handled by applications and libraries, a StackOverflowError could cause an application to stop. Users are recommended to upgrade to version 3.18.0, which fixes the issue.

A Regular Expression Denial of Service (ReDoS) vulnerability was discovered in the Hugging Face Transformers library, specifically within the DonutProcessor class's `token2json()` method. This vulnerability affects versions 4.50.3 and earlier, and is fixed in version 4.52.1. The issue arises from the regex pattern `<s_(.*?)>` which can be exploited to cause excessive CPU consumption through crafted input strings due to catastrophic backtracking. This vulnerability can lead to service disruption, resource exhaustion, and potential API service vulnerabilities, impacting document processing tasks using the Donut model.

Connect2id Nimbus JOSE + JWT 10.0.x before 10.0.2 and 9.37.x before 9.37.4 allows a remote attacker to cause a denial of service via a deeply nested JSON object supplied in a JWT claim set, because of uncontrolled recursion. NOTE: this is independent of the Gson 2.11.0 issue because the Connect2id product could have checked the JSON object nesting depth, regardless of what limits (if any) were imposed by Gson.

A remote code execution vulnerability (CVSS 7.5). High severity vulnerability requiring prompt remediation.

CVE-2025-52520 is an integer overflow vulnerability in Apache Tomcat's multipart upload handling that allows unauthenticated remote attackers to bypass size limits and trigger denial of service. The vulnerability affects Tomcat versions 11.0.0-M1 through 11.0.8, 10.1.0-M1 through 10.1.42, 9.0.0.M1 through 9.0.106, and EOL version 8.5.0 through 8.5.100, requiring only network access with no authentication. With a CVSS score of 7.5 (High severity) and an attack vector rated as Network/Low complexity, this represents a significant availability risk for unpatched deployments.

liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. Multiple secret-dependent branches have been identified in the reference implementation of the HQC key encapsulation mechanism when it is compiled with Clang for optimization levels above -O0 (-O1, -O2, etc). A proof-of-concept local attack exploits this secret-dependent information to recover the entire secret key. This vulnerability is fixed in 0.14.0.

Apache Tomcat contains a race condition vulnerability in the APR/Native connector that can be triggered during concurrent HTTP/2 connection handling, particularly when clients initiate connection closes. The vulnerability affects Tomcat 9.0.0.M1 through 9.0.106 (and EOL versions 8.5.0-8.5.100), allowing remote unauthenticated attackers to cause denial of service through improper synchronization of shared resources. With a CVSS score of 7.5 and network-accessible attack vector requiring no authentication, this represents a high-severity availability impact, though no active public exploitation has been confirmed.

CVE-2025-53020 is a late release of memory after effective lifetime vulnerability (use-after-free) in Apache HTTP Server versions 2.4.17 through 2.4.63 that allows unauthenticated remote attackers to cause denial of service with high availability impact. The vulnerability has a CVSS score of 7.5 (high severity) with network-accessible attack vector and low attack complexity, making it easily exploitable without authentication. Affected organizations running vulnerable Apache HTTP Server versions should prioritize upgrading to version 2.4.64 immediately.

CVE-2025-49812 is an HTTP request smuggling/desynchronization vulnerability in Apache HTTP Server's mod_ssl that allows man-in-the-middle attackers to hijack HTTPS sessions by exploiting improper handling of TLS upgrades. Only Apache HTTP Server versions through 2.4.63 with 'SSLEngine optional' configurations are affected, enabling session hijacking with high confidentiality and integrity impact. The vulnerability requires network-level access and careful timing but does not require user interaction or privileges; upgrade to 2.4.64 (which removes TLS upgrade support entirely) is the recommended mitigation.

CVE-2025-49630 is a denial of service vulnerability in Apache HTTP Server versions 2.4.26 through 2.4.63 that can be triggered by untrusted remote clients when a reverse proxy is configured with HTTP/2 backend support and ProxyPreserveHost enabled, causing an assertion failure that crashes the proxy process. The vulnerability has a CVSS score of 7.5 (High) with network-accessible attack vector and no authentication required, making it immediately exploitable by unauthenticated remote attackers.

CVE-2025-23048 is an authentication bypass vulnerability in Apache HTTP Server 2.4.35-2.4.63 affecting mod_ssl configurations with multiple virtual hosts using different client certificate restrictions. An attacker with valid client certificates trusted by one virtual host can exploit TLS 1.3 session resumption to access another restricted virtual host if SSLStrictSNIVHostCheck is not enabled, achieving unauthorized access to confidential information and potentially modifying data. This is a network-accessible vulnerability with no authentication required and high real-world impact.

CVE-2024-47252 is a security vulnerability (CVSS 7.5). High severity vulnerability requiring prompt remediation.

CVE-2024-43394 is a Server-Side Request Forgery (SSRF) vulnerability in Apache HTTP Server on Windows (versions 2.4.0-2.4.63) that allows unauthenticated remote attackers to leak NTLM credential hashes to malicious servers through unvalidated request input processed by mod_rewrite or Apache expressions. The vulnerability exploits Windows SMB/UNC path handling to trigger NTLM authentication, potentially compromising domain credentials. This is a high-severity issue affecting all default Windows installations without explicit UNC path filtering.

CVE-2024-43204 is a Server-Side Request Forgery (SSRF) vulnerability in Apache HTTP Server when mod_proxy is loaded, allowing unauthenticated attackers to initiate outbound proxy requests to attacker-controlled URLs. The vulnerability requires an uncommon configuration where mod_headers is used to modify Content-Type headers based on user-supplied HTTP request values. Apache recommends immediate upgrade to version 2.4.64 to remediate this high-integrity-impact issue.

HTTP response splitting vulnerability in Apache HTTP Server core allows network-based attackers without authentication to inject arbitrary HTTP headers and content into responses by manipulating Content-Type headers in proxied or hosted applications, potentially enabling cache poisoning, session hijacking, or XSS attacks. Affects Apache HTTP Server versions prior to 2.4.64, with a critical note that the initial patch in 2.4.59 was incomplete. This is a regression/incomplete fix of CVE-2023-38709, indicating patch evasion and suggesting active exploitation interest.

A remote code execution vulnerability in Git GUI (CVSS 8.5) that allows you. High severity vulnerability requiring prompt remediation.

CVE-2025-27614 is a command injection vulnerability in Gitk (Git's Tcl/Tk history browser) affecting versions 2.41.0 through 2.50.0 that allows arbitrary script execution with user privileges through specially crafted repository filenames. An attacker can exploit this via social engineering by tricking a user into invoking 'gitk filename' where the filename is maliciously structured to execute attacker-supplied scripts (shell, Perl, Python, etc.). With a CVSS score of 8.6 and no privilege requirement, this poses significant real-world risk for developers who clone untrusted repositories.

A vulnerability in the DocugamiReader class of the run-llama/llama_index repository, up to version 0.12.28, involves the use of MD5 hashing to generate IDs for document chunks. This approach leads to hash collisions when structurally distinct chunks contain identical text, resulting in one chunk overwriting another. This can cause loss of semantically or legally important document content, breakage of parent-child chunk hierarchies, and inaccurate or hallucinated responses in AI outputs. The issue is resolved in version 0.3.1.

CVE-2025-38348 is a buffer overflow vulnerability in the Linux kernel's p54 WiFi driver (wifi: p54) that allows a malicious or compromised USB device to trigger a memory overflow in the p54_rx_eeprom_readback() function by sending a crafted eeprom_readback message with an inflated length value. An attacker with local access and low privileges can cause denial of service or potentially execute code with kernel privileges; however, exploitation requires the device to first upload vendor firmware (proprietary and not widely distributed), which significantly limits real-world attack surface. The vulnerability is not currently tracked as actively exploited in CISA KEV catalog.

CVE-2025-38346 is a security vulnerability (CVSS 7.8). High severity vulnerability requiring prompt remediation. Vendor patch is available.

In the Linux kernel, the following vulnerability has been resolved: ACPICA: fix acpi operand cache leak in dswstate.c ACPICA commit 987a3b5cf7175916e2a4b6ea5b8e70f830dfe732 I found an ACPI cache leak in ACPI early termination and boot continuing case.

Continue to boot and log is omitted ... I analyzed this memory leak in detail and found acpi_ds_obj_stack_pop_and_ delete() function miscalculated the top of the stack. acpi_ds_obj_stack_push() function uses walk_state->operand_index for start position of the top, but acpi_ds_obj_stack_pop_and_delete() function considers index 0 for it. Therefore, this causes acpi operand memory leak. This cache leak causes a security threat because an old kernel (<= 4.9) shows memory locations of kernel functions in stack dump. Some malicious users could use this information to neutralize kernel ASLR. I made a patch to fix ACPI operand cache leak.

In the Linux kernel, the following vulnerability has been resolved: ACPICA: fix acpi parse and parseext cache leaks ACPICA commit 8829e70e1360c81e7a5a901b5d4f48330e021ea5 I'm Seunghun Han, and I work for National Security Research Institute of South Korea.

CVE-2025-38343 is a security vulnerability (CVSS 5.5). Remediation should follow standard vulnerability management procedures. Vendor patch is available.

CVE-2025-38341 is a double-free vulnerability in the Linux kernel's fbnic (Meta Fabric NIC) driver that occurs when DMA-mapping of a firmware message fails. An attacker with local access and low privilege can trigger this memory corruption to achieve code execution or denial of service. The vulnerability affects Linux kernels with the fbnic driver enabled, and while there is no current evidence of active exploitation in the wild, the high CVSS score (7.8) and local attack vector make this a moderate-to-high priority for systems running affected kernel versions.
