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.

kernel: wifi: mt76: mt7915: fix list corruption after hardware restart
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.
Statement: On mt76/mt7915, a full hardware restart recreated stations but failed to clear WCID and driver lists, leading to list corruption and potential crashes after ieee80211_restart_hw(). The fix adds mt76_reset_device() to reset all WCID entries (set wcid->sta = 0, detach and clean), clear list heads and masks, and re-init per-PHY TX lists before re

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
