Technical description

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

wifi: mt76: mt7915: fix list corruption after hardware restart

Since stations are recreated from scratch, all lists that wcids are added

to must be cleared before calling ieee80211_restart_hw.

Set wcid->sta = 0 for each wcid entry in order to ensure that they are

not added again before they are ready.

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.
