Last modified

CVE-2024-36355 is a high-severity vulnerability rated 7/10 on the CVSS scale. Improper input validation in the SMM handler could allow an attacker with Ring0 access to write to SMRAM and modify execution flow for S3 (sleep) wake up, potentially resulting in arbitrary code execution.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
