CVE-2024-36355
HighSummary
The vulnerability is due to improper input validation in the SMM handler, which could allow an attacker with Ring0 access to write to SMRAM and modify the execution flow during S3 (sleep) wake-up, potentially leading to arbitrary code execution.
Risk Assessment
The risk for the organization includes privilege escalation in a Ring0 environment, potentially allowing an attacker to take control of the system, bypass security measures, and persistently infect the firmware.
Recommendation
It is recommended to apply vendor-provided patches for hardware or firmware immediately and restrict Ring0 access to trusted processes.
