CVE-2024-57925

Kernel memory corruption via unchecked allocation failure

Published Jan 19, 2025 · Updated May 23, 2026

Memory corruption in the Linux ksmbd server allows local users to corrupt kernel memory and interrupt the operating system. smb2_send_interim_resp() fails to check whether ksmbd_alloc_work_struct() returned NULL before allocate_interim_rsp_buf() writes through in_work->response_buf. Reaching the flaw requires local low-privileged access and a failed work-structure allocation; the resulting write can corrupt kernel state or crash the system.
