AZL-72520 CVE-2025-68237 affecting package kernel for versions less than 6.6.119.3-1

In the Linux kernel, the following vulnerability has been resolved: mtdchar: fix integer overflow in read/write ioctls The "req.start" and "req.len" variables are u64 values that come from the user at the start of the function. We mask away the high 32 bits of "req.len" so that's capped at U32MAX...

CVE-2025-68237

CVE-2025-68237 : In the Linux kernel mtdchar read/write ioctls, user-supplied req.start (u64) can overflow when combined with req.len (masked to 32 bits), enabling an integer overflow. The fix uses check_add_overflow() to guard the addition. The advisory does not specify exploitation details or a...

SUSE CVE-2024-47740

In the Linux kernel, the following vulnerability has been resolved: f2fs: Require FMODEWRITE for atomic write ioctls The F2FS ioctls for starting and committing atomic writes check for inodeownerorcapable, but this does not give LSMs like SELinux or Landlock an opportunity to deny the write acces...

CVE-2024-47740

The CVE-2024-47740 issue affects the Linux kernel F2FS atomic-write ioctls. Previously, F2FS_IOC_START_ATOMIC_REPLACE/COMMIT_ATOMIC_WRITE could bypass LSM deny checks because inode_owner_or_capable() could return true when the caller’s FSUID matched the inode UID. The fix requires FMODE_WRITE for...
