CVE-2024-47740 f2fs: Require FMODE_WRITE for atomic write ioctls

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...

CVE-2024-47726

CVE-2024-47726 relates to the Linux kernel F2FS: a fix ensures all in-flight direct I/O (DIO) writes complete before removing blocks. The root cause was a race where a DIO could overwrite data in a block that would be reused by another inode if block removal occurred too early. Affected component...
