Overview

CVE-2026-93790 is a high-severity vulnerability. It was published on September 24, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

wifi: iwlwifi: mvm: fix out-of-bounds tid_data access in BA notif

mvmsta->tid_data was indexed by the TFD loop counter 'i' instead of

the actual TID value 'tid'. This writes lq_color into a random tid_data

slot unrelated to the BA entry.

Since multi-TID blockack is not really in use, 'i' was always 0 and no

harm was done.

Add a out-of-bound check before accessing the array.

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.
