CVE-2024-21944
MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk13th percentile - higher than 13% of all known CVEs
Summary
Improper input validation for DIMM SPD metadata could allow an attacker with physical access, ring0 access, or control over the Root of Trust for BIOS update to overwrite guest memory, resulting in loss of guest data integrity.
Risk Assessment
An attacker can compromise the integrity of virtual machines or guest systems, potentially leading to data corruption or unexpected behavior.
Recommendation
Apply patches from the motherboard/BIOS vendor. Ensure compatible DIMM modules are used and memory protection mechanisms are enabled.

Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
Original NVD description (English source)
Improper input validation for DIMM serial presence detect (SPD) metadata could allow an attacker with physical access, ring0 access on a system with a non-compliant DIMM, or control over the Root of Trust for BIOS update, to potentially overwrite guest memory resulting in loss of guest data integrity.
