Intel(R) Processor: Incorrect Behavior Order
CVE-2024-24853 is a high-severity incorrect behavior order vulnerability in Intel(R) Processor, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited with local access to the system by an attacker with administrator privileges, but only if a user takes part, for example by opening a link or file. Affected Intel(R) Processor versions: See references. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.23% 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
