| CVE-2026-43350 | Hig | 0.42 | 7.6 | 0.00 | May 8, 2026 | In the Linux kernel, the following vulnerability has been resolved: smb: client: require a full NFS mode SID before reading mode bits parse_dacl() treats an ACE SID matching sid_unix_NFS_mode as an NFS mode SID and reads sid.sub_auth[2] to recover the mode bits. That assumes… | ||
