In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Wake DMCUB before executing GPINT commands
[Why]
DMCUB can be in idle when we attempt to interface with the HW through
the GPINT mailbox resulting in a system hang.
[How]
Add dc_wake_and_execute_gpint() to wrap the wake, execute, sleep
sequence.
If the GPINT executes successfully then DMCUB will be put back into
sleep after the optional response is returned.
It functions similar to the inbox command interface.

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.
