Details

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.
