Intel(R) Arc(TM) & Iris(R) Xe Graphics software: Improper Neutralization of Invalid Characters in Identifiers in Web Pages

Published Updated By the CyberSecBulletin desk

CVE-2024-21864 is a high-severity improper neutralization of invalid characters in identifiers in web pages vulnerability in Intel(R) Arc(TM) & Iris(R) Xe Graphics software, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited from the same local network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected Intel(R) Arc(TM) & Iris(R) Xe Graphics software versions: before version 31.0.101.5081. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.34% 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. Update iris_xe_graphics to 31.0.101.5081 or a later version.
  2. Update arc_a_graphics to 31.0.101.5081 or a later version.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
