CVE-2026-23230

CVE-2026-23230 is a Linux kernel local race in the SMB/CIFS client code where cached_fid bitfields (is_open, has_lease, on_list) were updated via concurrent paths, causing read–modify–write races. The root cause is that these three flags shared a single byte, so an update to one could overwrite o...
