CVE-2026-43066

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ext4: fix iloc.bh leak in ext4_fc_replay_inode() error paths<br /> <br /> During code review, Joseph found that ext4_fc_replay_inode() calls<br /> ext4_get_fc_inode_loc() to get the inode location, which holds a<br /> reference to iloc.bh that must be released via brelse().<br /> <br /> However, several error paths jump to the &amp;#39;out&amp;#39; label without<br /> releasing iloc.bh:<br /> <br /> - ext4_handle_dirty_metadata() failure<br /> - sync_dirty_buffer() failure<br /> - ext4_mark_inode_used() failure<br /> - ext4_iget() failure<br /> <br /> Fix this by introducing an &amp;#39;out_brelse&amp;#39; label placed just before<br /> the existing &amp;#39;out&amp;#39; label to ensure iloc.bh is always released.<br /> <br /> Additionally, make ext4_fc_replay_inode() propagate errors<br /> properly instead of always returning 0.
