CVE-2023-1194 is fixed in linux on 1 platform, first by DEBIAN-CVE-2023-1194, released November 3, 2023. It is not reported as exploited. Patch Radar priority: High.
An out-of-bounds (OOB) memory read flaw was found in parse_lease_state in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. When an attacker sends the CREATE command with a malformed payload to KSMBD, due to a missing check of `NameOffset` in the `parse_lease_state()` function, the `create_context` object can access invalid memory.
