CriticalCVSS 9.8Exploitation Probability (EPSS)
Elevated risk59th percentile - higher than 59% of all known CVEs
Summary
A heap-based buffer overflow in Windows BitLocker allows an unauthorized attacker to execute code over a network. The vulnerability stems from improper memory handling during data processing.
Risk Assessment
An attacker could remotely execute arbitrary code in the context of the BitLocker service, potentially leading to full system compromise and access to encrypted data.
Recommendation
Apply the available Microsoft security updates for Windows BitLocker as soon as possible and restrict network access to the service.
