Description OSIDB Bzimport 2026-09-25 11:31:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ksmbd: propagate DACL parsing errors

parse_dacl() silently accepts truncated ACEs and allocation failures,
allowing set_info_sec() to continue with an incomplete ACL conversion.

Return parsing and allocation errors to parse_sec_desc() so malformed
security descriptors are rejected before inode attributes or ACL xattrs
are updated.
