Overview

CVE-2024-57925 is a high-severity vulnerability. It was published on January 19, 2025 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: fix a missing return value check bug

In the smb2_send_interim_resp(), if ksmbd_alloc_work_struct()

fails to allocate a node, it returns a NULL pointer to the

in_work pointer. This can lead to an illegal memory write of

in_work->response_buf when allocate_interim_rsp_buf() attempts

to perform a kzalloc() on it.

To address this issue, incorporating a check for the return

value of ksmbd_alloc_work_struct() ensures that the function

returns immediately upon allocation failure, thereby preventing

the aforementioned illegal memory access.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
