A problem with the implementation of the MACsec protocol in Palo Alto Networks PAN-OS® results in the cleartext exposure of the connectivity association key (CAK). This issue is only applicable to PA-7500 Series devices which are in an NGFW cluster.
A user who possesses this key can read messages being sent between devices in a NGFW Cluster. There is no impact in non-clustered firewalls or clusters of firewalls that do not enable MACsec.

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.
