CVE-2026-31709

In the Linux kernel SMB client (cifsacl), CVE-2026-31709 arises from insufficient validation of a server-provided DACL when rewriting security descriptors. The fix extends structural validation to ensure the DACL header, size, and per-ACE bounds are checked before any rewrite paths (replace_sids_...
