runc: Malicious image with /dev symlink can trigger limited host filesystem integrity violations

Impact When setting up the container rootfs, setupPtmx and setupDevSymlinks call os.Remove and os.Symlink with a filepath.Join string which allow an image with /dev as a symlink to trick runc into deleting files called ptmx on the host or creating a hardcoded set of symlinks with specific names a...

kernel: gfs2: Fix use-after-free in iomap inline data write path

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...

kernel: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...

kernel: wifi: mac80211: remove station if connection prep fails

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When Multi-Link Operation MLO connection preparation fails, the system may not correctly remove the associated station. This can lead to a use-after-free or double-free vulnerability in the debugfs component, potentially causing...

kernel: xfs: fix freemap adjustments when adding xattrs to leaf blocks

A flaw was found in the Linux kernel's XFS filesystem. When adding extended attributes xattrs, which are metadata associated with files, to leaf blocks, incorrect adjustments to the freemap can occur. This inconsistency allows the entries array and free space to overlap, leading to an assertion...

CVE-2025-66389

GitHub Copilot version 1.372.0 is vulnerable to unauthorized filesystem access outside of a workspace folder. The root cause is a file-handler URI parameter used in the fetch_webpage() function, which allows access without user approval. This flaw could lead to data exfiltration if an indirect pr...

CVE-2026-56446: Improper Control of Generation of Code

MISP allowed a site administrator to configure an arbitrary filesystem path for the NDJSON error log used by JsonLogTool. Because log entries can include attacker-controlled content, an authenticated attacker with site administrator privileges could direct log output to a PHP file in a...
