CVE-2024-8105
MediumCVSS 6.4Exploitation Probability (EPSS)
Low risk15th percentile - higher than 15% of all known CVEs
Summary
A vulnerability exists in UEFI implementations that use a hard-coded software-based Platform Key (PK). An attacker in possession of the corresponding PK private key can sign arbitrary UEFI executables or firmware components, causing them to be trusted by affected systems and potentially bypassing UEFI Secure Boot trust validation.
Risk Assessment
The risk involves bypassing Secure Boot, allowing an attacker to execute unauthorized code during the system boot process, potentially leading to persistent system compromise and installation of firmware-level malware.
Recommendation
Immediately apply patches provided by hardware/OEM vendors and update firmware to a version that does not use a hard-coded PK. Enforce the use of a hardware-based PK or properly manage platform keys.
