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.

kernel: memory leak for large arguments in video_usercopy function in drivers/media/v4l2-core/v4l2-ioctl.c
An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
A flaw memory leak in the Linux kernel webcam device functionality was found in the way user calls ioctl that triggers video_usercopy function. The highest threat from this vulnerability is to system availability.
Mitigation: To mitigate this issue, prevent the module v4l2-common from being loaded. Please see https://access.redhat.com/solutions/41278 for information on how to blacklist a kernel module to prevent it from loading automatically.
