Overview

CVE-2026-23246 is a high-severity vulnerability. It was published on March 18, 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: mac80211: bounds-check link_id in ieee80211_ml_reconfiguration

link_id is taken from the ML Reconfiguration element (control & 0x000f),

so it can be 0..15. link_removal_timeout[] has IEEE80211_MLD_MAX_NUM_LINKS

(15) elements, so index 15 is out-of-bounds. Skip subelements with

link_id >= IEEE80211_MLD_MAX_NUM_LINKS to avoid a stack out-of-bounds

write.

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.
