First published: Fri Dec 16 2022(Updated: )
An out-of-bounds (OOB) memory read flaw was found in parse_lease_state in KSMBD implemetation of in-kernel samba server and CIFS in the Linux kernel. When attacker sends CREATE command with malform payload to KSMBD, because of missing check `NameOffset` in function `parse_lease_state()`, the `create_context` object can access invalid memory.
