CVE-2023-54281

CVE-2023-54281 (Linux kernel, btrfs) : The issue affects the btrfs inode lookup path during ino_lookup ioctl. When ino_lookup triggers btrfs_iget() to obtain an inode reference while holding the root btree, it may need to acquire an additional lock on the same/btrfs root path, risking a deadlock ...
