Published Aug 8, 2023CWE-367EPSS 0.08%

Overview

CVE-2023-28576 is a medium-severity vulnerability. It was published on August 8, 2023 and has a CVSS 3.1 base score of 6.4 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.4, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

The buffer obtained from kernel APIs such as cam_mem_get_cpu_buf() may be readable/writable in userspace after kernel accesses it. In other words, user mode may race and modify the packet header (e.g. header.count), causing checks (e.g. size checks) in kernel code to be invalid. This may lead to out-of-bounds read/write issues.

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.
