Overview

CVE-2024-26694 is a high-severity vulnerability. It was published on April 3, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, 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:

wifi: iwlwifi: fix double-free bug

The storage for the TLV PC register data wasn't done like all

the other storage in the drv->fw area, which is cleared at the

end of deallocation. Therefore, the freeing must also be done

differently, explicitly NULL'ing it out after the free, since

otherwise there's a nasty double-free bug here if a file fails

to load after this has been parsed, and we get another free

later (e.g. because no other file exists.) Fix that by adding

the missing NULL assignment.

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.
