vGPU software (guest driver) - Linux, vGPU…: Out-of-bounds Read
CVE-2022-34676 is a high-severity out-of-bounds read vulnerability in vGPU software (guest driver) - Linux, vGPU software (Virtual GPU Manager), NVIDIA Cloud Gaming (guest driver), NVIDIA Cloud Gaming (Virtual GPU Manager) from NVIDIA, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. There is no confirmed exploitation so far. EPSS estimates a 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Virtual GPU to 11.11 or 13.6 or 14.4, whichever matches your release line, or a later version.
- Update Cloud Gaming to 525.60.11 or 525.60.12, whichever matches your release line, or a later version.
- Read the advisory on nvidia.custhelp.com for workarounds and exact fixed builds.
