CVE-2026-97586Hinoki check available

Unspecified impact via retained AFS directory mapping

Published Sep 25, 2026 · Updated Sep 25, 2026

Resource-release error in the Linux kernel 6.14 AFS client allows attackers to cause an unspecified impact during directory searches. The afs_dir_search_bucket() bad path returns without calling kunmap_local() for iter->block, leaving the directory block mapping retained. Reachability requires the AFS client and a directory search that enters this error path; the upstream disclosure does not specify the resulting consequence.
