In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix possible out-of-bound read in ath12k_htt_pull_ppdu_stats()
len is extracted from HTT message and could be an unexpected value in
case errors happen, so add validation before using to avoid possible
out-of-bound read in the following message iteration and parsing.
The same issue also applies to ppdu_info->ppdu_stats.common.num_users,
so validate it before using too.
These are found during code review.
Compile test only.

In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix possible out-of-bound read in ath12k_htt_pull_ppdu_stats()
len is extracted from HTT message and could be an unexpected value in
case errors happen, so add validation before using to avoid possible
out-of-bound read in the following message iteration and parsing.
The same issue also applies to ppdu_info->ppdu_stats.common.num_users,

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.
