Memory corruption in Linux kernel's algif_aead cryptographic interface allows local authenticated users to achieve arbitrary kernel memory read/write, leading to privilege escalation to root. The vulnerability stems from improper handling of in-place operations introduced in commit 72548b093ee3, affecting kernel versions from 4.14 through 6.19.x. Multiple public exploit codes exist including proof-of-concept demonstrations from security researchers, with EPSS score of 0.01% indicating currently low widespread exploitation likelihood despite POC availability.
Remote code execution in Xerte Online Toolkits 3.15 and earlier allows unauthenticated attackers to upload and execute arbitrary PHP code by chaining an incomplete file extension filter bypass (.php4 extension) with authentication bypass and path traversal vulnerabilities in the elFinder connector endpoint. Attackers can achieve complete server compromise by uploading malicious PHP files, renaming them with the .php4 extension to evade filtering, and executing operating system commands. Vendor-released patches available via three GitHub commits (02661be, 17e4f94, 507d55c). No public exploit code or active exploitation confirmed at time of analysis, though the attack chain is straightforward for skilled attackers.
Unauthenticated attackers can execute remote code and read arbitrary files in Xerte Online Toolkits 3.15 and earlier via a missing authentication flaw in the elFinder connector endpoint. The vulnerability stems from a logic error where HTTP redirects for unauthenticated requests fail to terminate PHP execution, allowing full server-side processing of file operations. Attackers can create directories, upload files, rename, duplicate, overwrite, and delete files in project media directories without authentication. When chained with path traversal and extension blocklist bypasses, this enables complete system compromise. VulnCheck identified the flaw, and vendor patches are available via three GitHub commits addressing versions 3.13.0 through 3.15.0.
Path traversal in Xerte Online Toolkits' elFinder connector allows authenticated attackers to move files to arbitrary filesystem locations, enabling application file overwrites, stored XSS, or chained remote code execution. Affects versions 3.15 and earlier through unsanitized rename operations at /editor/elfinder/php/connector.php. Vendor patches available via GitHub commits 02661be, 507d55c, and 17e4f94. CVSS 7.1 with low attack complexity and low privileges required. No public exploitation confirmed (SSVC: exploitation=none), but attack is not automatable per CISA framework.
Xerte Online Toolkits versions 3.15 and earlier expose the server-side filesystem root path through an unauthenticated GET request to the /setup page, allowing remote attackers to retrieve sensitive path information rendered in HTML responses. This information disclosure enables exploitation of path-dependent vulnerabilities such as relative path traversal in connector.php, potentially leading to unauthorized file access or further system compromise.
Local privilege escalation in Linux Kernel ext4 filesystem allows authenticated users to trigger kernel crashes and potentially execute arbitrary code with high privileges. The vulnerability stems from improper handling of inline data conversion when truncate() operations exceed inline storage capacity in ext4 filesystems. Affected kernel versions include mainline through 7.0-rc3 and stable branches 5.10.x through 6.19.x, with vendor patches available across all active kernel series. EPSS exploitation probability is very low (0.02%, 7th percentile) and no public exploit identified at time of analysis, though CVSS 7.8 reflects high local impact if exploited.
ThinkPHP 5.0.23 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary PHP code by invoking functions through the routing parameter. Rated critical severity (CVSS 9.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
ELBA5 5.8.0 contains a remote code execution vulnerability that allows attackers to obtain database credentials and execute arbitrary commands with SYSTEM level permissions. Rated critical severity (CVSS 9.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Template injection combined with AngularJS 1.5.2 sandbox escape primitives in Beghelli Sicuro24 SicuroWeb enables arbitrary JavaScript execution in operator browsers, leading to session hijacking and persistent compromise. Network-adjacent attackers can exploit this via MITM on plaintext HTTP deployments requiring only passive user interaction. Publicly available POC exists (CVE-2026-22191 exploit chain documented by BoffSec Services and kmkz), confirming weaponization risk. CVSS 9.3 reflects adjacent-network access requirement (AV:A), but SSVC indicates total technical impact with POC-confirmed exploitation status.
Remote code execution via unauthenticated command injection in rclone's remote control API allows network attackers to execute arbitrary commands on the host system through a single HTTP request. The vulnerability affects rclone deployments with the RC API enabled (--rc or rclone rcd) that are network-accessible and lack global HTTP authentication. An attacker exploits the unprotected operations/fsinfo endpoint by crafting a WebDAV backend definition with a malicious bearer_token_command parameter, which executes during backend initialization. Confirmed exploitable on master branch (commit bf55d5e6) and release v1.73.4 with public proof-of-concept available. CVSS 9.2 reflects critical severity with network attack vector and no authentication required, though exploitation requires specific deployment configuration (AT:P). No CISA KEV listing or EPSS data available at time of analysis.
Authentication bypass in rclone's remote control (RC) API allows network attackers to disable authorization checks via unauthenticated configuration mutation, enabling full administrative access to RC endpoints. The `options/set` endpoint lacks authentication requirements and permits setting `rc.NoAuth=true`, which disables protection for all RC methods marked `AuthRequired: true`. Affects rclone v1.45 onward when RC is network-accessible without HTTP authentication. No CISA KEV listing or public exploit code identified at time of analysis, though GitHub security advisory provides detailed proof-of-concept reproduction steps. CVSS 9.2 reflects critical severity with network vector and no authentication required, though CVSS:4.0 AT:P (Attack Requirements: Present) indicates specific deployment prerequisites limit automatic exploitation.
Path traversal in EspoCRM's formula scripting engine allows authenticated administrators to achieve arbitrary file read/write on the web server by manipulating attachment sourceId fields. The vulnerability chains unsanitized user input with filesystem operations, enabling admins to overwrite or access files anywhere within PHP's open_basedir restriction. Publicly available exploit code exists. Vendor-released patch version 9.3.4 addresses this critical issue. Despite the 9.1 CVSS score and Changed scope indicating potential container escape or cross-tenant impact, EPSS data was not provided to assess real-world exploitation likelihood.
Local privilege escalation in PackageKit 1.0.2-1.3.4 allows unprivileged Linux users to install arbitrary RPM packages as root without authentication via TOCTOU race condition on transaction flags. The vulnerability exploits three synchronized bugs in the transaction state machine: unconditional flag overwrite, silent state-transition rejection that leaves corrupted flags, and late flag validation at dispatch time. Actively exploited in targeted attacks according to vendor advisory. CVSS 8.8 with scope change reflects full system compromise from low-privileged account. Patched in version 1.3.5.
LanSpy 2.0.1.159 contains a local buffer overflow vulnerability that allows attackers to overwrite the instruction pointer by supplying oversized input to the scan field. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
LanSpy 2.0.1.159 contains a local buffer overflow vulnerability in the scan section that allows local attackers to execute arbitrary code by exploiting structured exception handling mechanisms. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Iperius Backup 5.8.1 contains a local buffer overflow vulnerability in the structured exception handling (SEH) mechanism that allows local attackers to execute arbitrary code by supplying a malicious. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
MAGIX Music Editor 3.1 contains a buffer overflow vulnerability in the FreeDB Proxy Options dialog that allows local attackers to execute arbitrary code by exploiting structured exception handling. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Terminal Services Manager 3.1 contains a stack-based buffer overflow vulnerability in the computer names field that allows local attackers to execute arbitrary code by triggering structured exception. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Command injection in radare2 PDB parser (versions before 6.1.4) enables arbitrary OS command execution when users analyze malicious PDB files. Publicly available exploit code exists. Attackers craft PDB files with newline characters in symbol names to inject radare2 commands during flag renaming operations, which then execute OS commands via radare2's shell operator when victims run the 'idp' command. CVSS 8.4 reflects local attack vector requiring user interaction, though EPSS data not available. Patch released in version 6.1.4 with detailed technical disclosure at blog.calif.io showing 0-day discovery process.
SQL injection in NocoBase's @nocobase/database package allows authenticated users with record-creation privileges to execute arbitrary SQL queries and extract database credentials. The vulnerability exists in the queryParentSQL() function, which constructs recursive Common Table Expression (CTE) queries using string concatenation instead of parameterized queries when processing tree collections with string primary keys. An attacker can inject malicious SQL by creating records with crafted primary key values, triggering the vulnerability when recursive eager loading occurs. Successful exploitation leads to full database compromise, with confirmed extraction of administrator credentials (emails and password hashes) in testing against PostgreSQL. On databases where the service account has elevated privileges, attackers can achieve operating system command execution via PostgreSQL's COPY...TO PROGRAM feature. Vendor patch available via GitHub PR #9133.
Cross-Site Request Forgery (CSRF) in GitLab CE/EE allows remote unauthenticated attackers to execute GraphQL mutations as authenticated victims through crafted web pages. Affects all versions from 17.0 through 18.11.0, with publicly available exploit code (HackerOne report 3627285). Despite high CVSS 8.1, exploitation requires user interaction (phishing/social engineering) and is not automatable per CISA SSVC framework. No evidence of active exploitation in CISA KEV at time of analysis. Vendor patches released: 18.9.6, 18.10.4, and 18.11.1.
Cross-site scripting vulnerability in GitLab's Storybook development environment allows remote unauthenticated attackers to steal access tokens via crafted user interaction. Affects GitLab CE/EE versions 16.1.0 through 18.9.5, 18.10 through 18.10.3, and 18.11.0. Publicly available exploit code exists (HackerOne report 3574642), though CISA SSVC indicates no confirmed active exploitation at time of analysis. CVSS 8.0 reflects high confidentiality and integrity impact with scope change, but CVSS vector AC:H (high complexity) and UI:R (user interaction required) indicate exploitation requires targeted social engineering rather than automated mass exploitation.
Cross-site scripting (XSS) in GitLab CE/EE versions 18.10.0-18.10.3 and 18.11.0 enables unauthenticated attackers to execute arbitrary JavaScript in victim browser sessions via improper path validation. GitLab disclosed this vulnerability with publicly available exploit code (HackerOne report 3572231), though CISA SSVC indicates no active exploitation confirmed at time of analysis. CVSS 8.0 reflects the changed scope (S:C) allowing impact beyond the vulnerable component, though High attack complexity (AC:H) and required user interaction (UI:R) limit ease of exploitation. Patched in versions 18.10.4 and 18.11.1.
Denial of service in Linux kernel ext4 filesystem allows remote attackers to trigger infinite loops and system hangs (143+ second inode lock blocking) via crafted mkdir/mknod operations. The vulnerability stems from incomplete cleanup when extent insertion fails - ext4_ext_map_blocks() reclaims physical blocks without deleting stale extent tree entries, causing reuse of blocks already allocated to xattrs. This triggers infinite loops in ext4_xattr_block_set() that hold inode locks indefinitely. With CVSS 9.4 (AV:N/AC:L/PR:N/UI:N) but EPSS only 0.02% (percentile 7), the network attack vector rating appears inconsistent with typical local filesystem exploitation. Patches available across stable kernel branches 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and mainline 7.0. No active exploitation confirmed (not in CISA KEV), but tagged for denial-of-service impact.
Recursive chmod operations can bypass --preserve-root protection in uutils coreutils versions prior to 0.6.0, allowing local authenticated users to execute destructive permission changes across the entire root filesystem. The vulnerability stems from incomplete path canonicalization that permits path traversal variants (/../) and symbolic links to circumvent safety checks, potentially causing system-wide denial of service. EPSS score of 0.01% indicates minimal exploitation probability in the wild, with no public exploit code identified and vendor patch available in version 0.6.0.
SQL injection in NocoBase plugin-collection-sql allows authenticated users with collection management permissions to bypass validation controls and execute arbitrary SQL queries. The checkSQL() function blocks dangerous keywords on collection creation and execution but is completely absent from the update endpoint, enabling attackers to create benign SQL collections then modify them with malicious queries to exfiltrate sensitive data including user credentials. Vendor patch available via GitHub PR #9134 and commit 851aee5. CVSS 7.2 reflects high privileges required (PR:H), but real-world impact is severe for environments where collection managers are not fully trusted administrators.
Path traversal in EspoCRM admin template management allows authenticated administrators to read, create, overwrite, or delete arbitrary files on the server filesystem. The vulnerability affects all versions prior to 9.3.4 and stems from unsanitized `name` and `scope` parameters in template path construction. Publicly available exploit code exists (GitHub security advisory GHSA-44c3-xjfp-3jrh), though no CISA KEV listing or confirmed active exploitation. CVSS 7.2 reflects high impact across confidentiality, integrity, and availability, but exploitation requires high-privilege (admin) access, significantly limiting real-world exposure to insider threats or compromised admin credentials.
Local privilege escalation in uutils coreutils mkfifo allows authenticated users to downgrade permissions on arbitrary files to world-readable mode. When mkfifo attempts to create a FIFO at a path where a file already exists, it erroneously continues execution and calls set_permissions on the existing file, changing its mode to default (typically 644 after umask). This can expose sensitive files like SSH private keys (~/.ssh/id_rsa) or application secrets to unauthorized local users. CISA SSVC confirms proof-of-concept code exists with total technical impact, though EPSS data is not available and the vulnerability is not yet in CISA KEV, indicating exploitation remains theoretical rather than widespread.
Textpad 8.1.2 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an excessively long buffer string through the Run command interface. Rated medium severity (CVSS 6.9), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
UltraISO 9.7.1.3519 contains a local buffer overflow vulnerability in the Output FileName field of the Make CD/DVD Image dialog that allows attackers to overwrite SEH and SE handler records. Rated medium severity (CVSS 6.9), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Angry IP Scanner 3.5.3 contains a buffer overflow vulnerability in the preferences dialog that allows local attackers to crash the application by supplying an excessively large string. Rated medium severity (CVSS 6.9), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

Rated medium severity (CVSS 6.9), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Race condition in Linux kernel ext4 filesystem allows denial of service through kernel panic when fast commit feature processes incompletely initialized journal inodes. Affects Linux kernel versions from 3.11 through multiple stable branches (5.10.x, 5.15.x, 6.1.x, 6.6.x, 6.12.x, 6.18.x, 6.19.x) prior to patched versions released in early 2025. Vendor patches available across all affected stable branches. EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. Not listed in CISA KEV, and no public exploit code identified at time of analysis. CVSS 8.8 reflects authenticated network attack vector, though real-world risk limited to systems where attackers have filesystem write access and ext4 fast commit is enabled.
Denial of service in GitLab CE/EE versions 12.3 through 18.11.0 allows authenticated users to trigger excessive resource consumption during issue import operations due to improper input validation on user-supplied data. The vulnerability affects all minor versions from 12.3 onwards until patched versions 18.9.6, 18.10.4, and 18.11.1. Publicly available exploit code exists, and CISA SSVC assessment indicates the vulnerability is exploitable but not automatable at scale.
Authenticated users can trigger denial of service in GitLab CE/EE versions 10.6 through 18.11.0 by sending crafted requests to the discussions endpoint that exhaust server resources. The vulnerability requires valid authentication credentials and affects all affected versions across the 10.6, 18.9, 18.10, and 18.11 release branches. Publicly available exploit code exists; CISA has not yet listed this in the Known Exploited Vulnerabilities catalog, but active exploitation likelihood is moderate given public POC availability and the low complexity of resource exhaustion attacks.
Authenticated users can trigger denial of service in GitLab by overwhelming system resources through the GraphQL API due to insufficient resource allocation limits. Affected versions span from 12.4 through 18.11.0 across three release branches. Publicly available exploit code exists, though active exploitation has not been confirmed in CISA KEV. CVSS 6.5 reflects moderate severity with high availability impact but requires valid authentication.
Denial of service in GitLab CE/EE affects authenticated users who can trigger resource exhaustion when retrieving notes under specific conditions, causing service unavailability. Versions 9.2 through 18.9.5, 18.10.0 through 18.10.3, and 18.11.0 are vulnerable. An authenticated attacker with standard user privileges can exploit this remotely without user interaction via crafted note retrieval requests. A publicly available exploit exists, and patches have been released by GitLab.
Complete authentication bypass in openvpn-auth-oauth2 plugin mode (v1.26.3-1.27.2) grants VPN access to unauthenticated clients. Legacy OpenVPN clients lacking WebAuth/SSO support bypass OIDC authentication entirely and gain full network access due to incorrect plugin return codes. Only the experimental shared-library plugin deployment is affected; the default management-interface mode is not vulnerable. Vendor patch released in v1.27.3 with confirmed fix commits. No active exploitation reported, but trivial to exploit with standard Linux openvpn CLI against vulnerable deployments.
Remote code execution in Progress Telerik UI for ASP.NET AJAX via insecure deserialization in the RadFilter control allows unauthenticated remote attackers to execute arbitrary code on the server by tampering with exposed client-side filter state. Affected versions span 2024.4.1114 through 2026.1.421. EPSS data not available; no public exploit or CISA KEV listing identified at time of analysis. The CVSS 8.1 (High) reflects network accessibility but 'High' attack complexity (AC:H), indicating successful exploitation requires specific conditions beyond simple network access.
F Prime framework before version 4.2.0 allows remote code execution via integer overflow in bounds checking combined with path traversal in file upload functionality. An attacker sending a crafted DataPacket with byteOffset=0xFFFFFF9C and dataSize=100 causes U32 addition to wrap to zero, bypassing the fileSize validation. This enables writing arbitrary data to any file at any offset on the target system, leading to remote code execution on embedded spaceflight and other critical systems. CISA KEV status and active exploitation unknown; vendor patch available in version 4.2.0.
Stack-based buffer overflow in Dell PowerProtect Data Domain DD OS allows remote unauthenticated attackers to execute arbitrary commands on vulnerable appliances. Affects Feature Release versions 7.7.1.0-8.6, LTS2025 (8.3.1.0-8.3.1.10), and LTS2024 (7.13.1.0-7.13.1.60). Despite network-accessible attack vector (AV:N/PR:N), high attack complexity (AC:H) indicates specialized exploit conditions. CISA SSVC framework rates exploitation as 'none' and automatable as 'no', suggesting manual, targeted exploitation rather than mass scanning. No active exploitation confirmed at time of analysis. Dell has released patches across all affected release tracks (DSA-2026-060).
Out-of-bounds write in the Linux kernel macb Ethernet driver allows local authenticated users with low privileges to corrupt kernel memory, potentially leading to privilege escalation, denial of service, or information disclosure. The vulnerability affects the ethtool statistics collection path where gem_get_ethtool_stats() writes statistics for MACB_MAX_QUEUES regardless of the actual number of active queues, causing a 760-byte buffer overflow when fewer queues are configured. KASAN validation confirms heap corruption with a write beyond allocated vmalloc region boundaries. No active exploitation confirmed (not in CISA KEV), and EPSS score is low (0.03%, 10th percentile), indicating minimal observed exploitation activity. Patches available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0).
Information disclosure and memory corruption in the Linux kernel's in-kernel SMB3 server (ksmbd) arises from smb2_calc_max_out_buf_len() being called with a hardcoded header length instead of the true offsetof() of the response ->Buffer field, after the read-compound rework in commit e2b76ab8b5c9. On affected kernels running ksmbd (6.6 through 7.0-rc3, plus stable backports), a miscalculated maximum output buffer length can cause the server to over-read into the response IOV, leaking adjacent kernel memory to an SMB client or corrupting response buffers. No public exploit identified at time of analysis, and EPSS is very low (0.03%, 9th percentile), consistent with a niche, non-default kernel subsystem rather than mass exploitation.
Authorization bypass in Sendmachine for WordPress plugin (versions ≤1.0.20) allows unauthenticated remote attackers to overwrite SMTP configuration settings without authentication. Attackers can redirect all outbound emails from WordPress sites - including password reset tokens and sensitive communications - to attacker-controlled servers, enabling credential theft and account takeover. CVSS 9.8 (Critical) reflects network attack vector with no authentication or user interaction required. No active exploitation confirmed at time of analysis, though the straightforward attack path (single HTTP request to exposed admin function) makes this a high-priority remediation target for sites using this plugin.
Use-after-free in Linux kernel Open vSwitch module causes system crash when deleting network interfaces on PREEMPT_RT kernels. The vulnerability is confirmed patched in multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0) with upstream fixes available via kernel.org commits. EPSS score of 0.02% (7th percentile) indicates very low exploitation likelihood. No active exploitation confirmed (not in CISA KEV). Local authenticated access required (CVSS AV:L/PR:L) with high impact (CVSS 7.8), but exploitation depends on PREEMPT_RT kernel configuration and specific Open vSwitch teardown race conditions.
Double-free vulnerability in Linux kernel SMC (Shared Memory Communications) splice handling allows local authenticated attackers to trigger use-after-free conditions and kernel panic. The flaw occurs when tee(2) duplicates an SMC pipe buffer: both the original and cloned pipe_buffer share the same smc_spd_priv pointer, causing smc_rx_pipe_buf_release() to free the same memory twice on pipe cleanup. This escalates from KASAN-detected slab-use-after-free to NULL pointer dereference in smc_rx_update_consumer(), resulting in denial of service via kernel crash. Vendor patches available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS exploitation probability is low (0.02%, 7th percentile) with no public exploit or CISA KEV listing at time of analysis.
Use-after-free in Linux kernel packet socket handling allows local attackers with low privileges to achieve kernel memory corruption, potentially leading to privilege escalation, information disclosure, or denial of service. The vulnerability stems from a race condition in packet_release() where NETDEV_UP events can re-register a socket into a fanout group's array after cleanup begins but before the socket number is zeroed, leaving dangling pointers. Patches are available across multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score is low (0.02%, 7th percentile) and no active exploitation is confirmed (not in CISA KEV), suggesting limited real-world exploitation despite high CVSS 7.8 rating.
Use-after-free in Linux kernel SPI subsystem (fsl_lpspi driver) causes NULL pointer dereference when DMA channels are torn down while SPI transfers are active. Local attackers with low privileges can trigger denial of service or potentially execute arbitrary code on affected systems running Linux kernel versions from 4.10 through 7.0-rc2, particularly impacting embedded and IoT devices using Freescale LPSPI controllers. EPSS score of 0.02% indicates very low observed exploitation probability, and no public exploit code or active exploitation has been identified at time of analysis. Vendor-released patches available across all affected stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0).
Use-after-free in Linux kernel virtio_net driver allows local authenticated attackers with low privileges to potentially achieve high confidentiality, integrity, and availability impact. The flaw triggers when virtio_net is configured with napi_tx=N (non-NAPI transmit mode) and the IFF_XMIT_DST_RELEASE flag is cleared by tc route filter rules. When a network namespace is destroyed while packets remain queued in the virtio transmit ring, the freed dst_ops structure is later dereferenced during packet cleanup, causing kernel memory corruption. Vendor patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (7th percentile) suggests low probability of mass exploitation, and no active exploitation or public POC has been identified at time of analysis.
Linux kernel ext4 filesystem allows mounting of maliciously crafted filesystems with bigalloc and non-zero s_first_data_block, potentially triggering memory corruption or information disclosure. Affects all Linux kernel versions from 2.6.12 (commit 1da177e) through 7.0, with patches released in stable branches 5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, and 6.19.11. CVSS 7.8 indicates high severity with local access and user interaction required. EPSS score of 0.02% (7th percentile) suggests low probability of widespread exploitation, and no active exploitation confirmed (not in CISA KEV).
