In the Linux kernel, the following vulnerability has been resolved:
drm/xe/vf: Don't expose sysfs attributes not applicable for VFs
VFs can't read BMG_PCIE_CAP(0x138340) register nor access PCODE
(already guarded by the info.skip_pcode flag) so we shouldn't
expose attributes that require any of them to avoid errors like:
[] xe 0000:03:00.1: [drm] Tile0: GT0: VF is trying to read an \
inaccessible register 0x138340+0x0

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.
