CVE-2026-46175 f2fs: fix fsck inconsistency caused by FGGC of node block

In the Linux kernel, the following vulnerability has been resolved: f2fs: fix fsck inconsistency caused by FGGC of node block During FGGC node block migration, fsck may incorrectly treat the migrated node block as fsync-written data. The reproduction scenario: root@vm:/mnt/f2fs seq 1 2048 | xargs...

CVE-2026-46160

CVE-2026-46160 concerns the Linux kernel’s Btrfs filesystem: when removing a directory, last_unlink_trans is not updated, which can lead to incorrect fsync behavior if a directory with an open file descriptor is fsynced after removal. This can cause log replay during mount to fail with -EIO, pote...

CVE-2026-46124

CVE-2026-46124 affects the Linux kernel isofs filesystem. The vulnerability arises because isofs_fh_to_dentry/isofs_fh_to_parent pass an attacker-controlled block number from an NFS file handle to isofs_export_iget(), which only rejects block == 0 before calling isofs_iget and sb_bread. A crafted...
