Technical description

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

wifi: cfg80211: fix buffer overflow in elem comparison

For vendor elements, the code here assumes that 5 octets

are present without checking. Since the element itself is

already checked to fit, we only need to check the length.

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.
