Noroxi assessment

Priority: Monitor (action score 29/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.7% (FIRST EPSS); higher than 77.4% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: nvidia-graphics-drivers (Debian:12) 460.32.03-1; nvidia-graphics-drivers (Debian:9) 390.144-1~deb9u1.

Low priority for now. Upgrade to nvidia-graphics-drivers (Debian:12) 460.32.03-1; nvidia-graphics-drivers (Debian:9) 390.144-1~deb9u1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

NVIDIA GPU Display Driver for Linux, all versions, contains a vulnerability in the kernel mode layer (nvidia.ko) in which it does not completely honor operating system file system permissions to provide GPU device-level isolation, which may lead to denial of service or information disclosure.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
