CVE-2024-46751 is a vulnerability in the Linux kernel's btrfs filesystem code where a BUG_ON() call occurs when a zero reference count is encountered in btrfs_lookup_extent_info(). This has been fixed by replacing the BUG_ON() with error handling that returns -EUCLEAN, aborts the transaction, and logs an error message. The vulnerability has a medium severity score of 5.5 and affects local attackers with low privileges. It does not impact confidentiality or integrity but can cause availability issues due to kernel crashes.
