CVE-2025-29950
HighSummary
CVE-2025-29950 is caused by improper input validation in System Management Mode (SMM). A privileged attacker could exploit this flaw to overwrite stack memory, potentially leading to arbitrary code execution.
Risk Assessment
The risk to the organization includes potential takeover of the system by a privileged attacker, which could compromise data integrity and confidentiality and lead to privilege escalation.
Recommendation
It is recommended to apply vendor-provided patches immediately and restrict privileged access to systems to minimize the risk of exploitation.
