A deadlock vulnerability was identified and fixed in the ext4 filesystem code of the Linux kernel. The issue involved an ABBA deadlock between concurrent extended attribute (xattr) workloads and the eviction thread during inode cache lookups. The fix introduces a non-blocking inode lookup flag to prevent waiting on inodes being evicted or created, thereby breaking the deadlock cycle.
