A flaw was found in the VirGL virtual OpenGL renderer (virglrenderer). The virgl did not properly initialize memory when allocating a host-backed memory resource. A malicious guest could use this flaw to mmap from the guest kernel and read this uninitialized memory from the host, possibly leading to information disclosure.

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 i

CVE-2022-0175 [HIGH] virglrenderer vulnerabilities
Title: virglrenderer vulnerabilities
Summary: Several security issues were fixed in virglrenderer.
It was discovered that virglrenderer incorrectly handled memory. An
attacker inside a guest could use this issue to cause virglrenderer to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2022-0135)
It was discovered that virglrenderer incorrectly initialized memory. An
attacker inside a guest could possibly use this issue to obtain sensitive
host information. (CVE-2022-0175)
Instructions: After a standard system update you need to restart all virtual machines to
make all the necessary changes.
