CVE-2026-98452

The Linux kernel contains a vulnerability in the SMB client where open_cached_dir() fails to properly handle compound requests. Specifically, if a CREATE succeeds but a subsequent command in the compound request returns an error, the system fails to retain the CREATE FID for proper cleanup using ...
