CVE-2026-43066
Description
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix iloc.bh leak in ext4_fc_replay_inode() error paths
During code review, Joseph found that ext4_fc_replay_inode() calls ext4_get_fc_inode_loc() to get the inode location, which holds a reference to iloc.bh that must be released via brelse().
However, several error paths jump to the 'out' label without releasing iloc.bh:
- ext4_handle_dirty_metadata() failure
- sync_dirty_buffer() failure
- ext4_mark_inode_used() failure
- ext4_iget() failure
Fix this by introducing an 'out_brelse' label placed just before the existing 'out' label to ensure iloc.bh is always released.
Additionally, make ext4_fc_replay_inode() propagate errors properly instead of always returning 0.
