Local service interruption via mismatched pool cleanup
Published Nov 5, 2024 · Updated Aug 5, 2026
Improper CIFS memory-pool cleanup in Linux 6.10 through 6.11.5 allows local users to interrupt service during CIFS module initialization. The init_cifs error path passes cifs_io_request_pool to mempool_destroy even though that pool was not created by mempool_create, triggering a free_large_kmalloc warning. Exploitation requires low-privilege local access and the CIFS initialization path; the documented consequence is a kernel availability failure.
