Local system hang via inode eviction deadlock
Published Sep 4, 2024 · Updated May 11, 2026
Improper locking in the Linux kernel VFS allows local users to hang the system by racing inode reclaim with inode eviction. prune_icache_sb marks reclaimable inodes I_FREEING before dispose_list, while ext4_evict_inode or ubifs_jnl_write_inode can look up an isolated xattr inode and wait on the state that the blocked traversal must clear. Reachability requires low-privileged local access, a timing race, and ext4 with ea_inode or UBIFS with xattrs; the bounded impact is a deadlocked system.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
