AMD Radeon™ RX 7000 Series Graphics Products: Improper Verification of Cryptographic Signature

Published Updated By the CyberSecBulletin desk

CVE-2024-36334 is a high-severity improper verification of cryptographic signature vulnerability in AMD Radeon™ RX 7000 Series Graphics Products from AMD, with a CVSS 4.0 base score of 7.0 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. There is no confirmed exploitation so far. EPSS estimates a 0.08% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Check which version of AMD Radeon™ RX 7000 Series Graphics Products you run against the affected versions below, and install the vendor's latest release.
  2. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
