CVE-2022-50270

This CVE (CVE-2022-50270) affects the Linux kernel f2fs component. The root cause was a faulty iocb assignment in the f2fs_direct_IO_enter trace event: the code only copied the pointer of iocb and then accessed its field during trace printing, which could lead to a kernel paging fault. The fixes ...

CVE-2025-21754

The CVE-2025-21754 affects Linux kernel btrfs behavior. When a direct IO write triggers a transaction abort, ordered extents are marked with BTRFS_ORDERED_IOERR, and if an ordered extent still has bytes remaining, btrfs_split_ordered_extent() asserts on flags. The documented root cause is an asse...
