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-2024-47741

In CVE-2024-47741, the Linux kernel’s btrfs code had a race when multiple threads perform lseek (SEEK_DATA/SEEK_HOLE) on the same file descriptor. The bug stems from find_desired_extent() grabbing the file’s private_data while it may be NULL, allowing two threads to allocate separate file private...

CVE-2024-47740

The CVE-2024-47740 entry concerns the Linux kernel F2FS: atomic write ioctls (F2FS_IOC_START_ATOMIC_REPLACE, F2FS_IOC_COMMIT_ATOMIC_WRITE, F2FS_IOC_START_ATOMIC_WRITE, F2FS_IOC_ABORT_ATOMIC_WRITE). The root cause is that inode_owner_or_capable() can incorrectly grant write access to processes whe...

CVE-2024-47726

CVE-2024-47726 concerns the Linux kernel F2FS: the fix ensures awaiting all Dio write I/Os before block removal to prevent data overwrite when blocks are reused by inodes. Affected are older kernel builds; patched versions exist (e.g., Debian linux-6.1 with the fix, Astra Linux SE18 bulletin, CBL...

CVE-2024-47690

The CVE-2024-47690 entry concerns the Linux kernel f2fs component. The vulnerability arises from the online repair mechanism for corrupted directories in f2fs_lookup(), which can generate dirty data/meta during races with readonly remount. This can leave dirty inodes after the filesystem becomes ...
