In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: fix race between cancel_hw_scan and hw_scan completion
The rtwdev->scanning flag isn't protected by mutex originally, so
cancel_hw_scan can pass the condition, but suddenly hw_scan completion
unset the flag and calls ieee80211_scan_completed() that will free
local->hw_scan_req. Then, cancel_hw_scan raises null-ptr-deref and
use-after-free. Fix it by moving the check condition to where
protected by mutex.

In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: fix race between cancel_hw_scan and hw_scan completion
The rtwdev->scanning flag isn't protected by mutex originally, so
cancel_hw_scan can pass the condition, but suddenly hw_scan completion
unset the flag and calls ieee80211_scan_completed() that will free
local->hw_scan_req. Then, cancel_hw_scan raises null-ptr-deref and
use-after-free. Fix it by moving the check condition to where
protected by mutex.
KASAN: null-ptr-deref in range [0x0000000000000088-0x000000000000008f]

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.
