GHSA-53PC-8XR3-68WX

Vulnerability from github – Published: 2023-11-03 09:32 – Updated: 2024-08-21 18:31

Details

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.

Severity ?

7.1 (High)
