CVE-2026-96909

Summary

A heap-based buffer overflow in Windows BitLocker allows remote attackers to execute arbitrary code on affected systems by sending specially crafted network requests. This vulnerability is particularly dangerous because it can be exploited without authentication and affects BitLocker's network communication functionality.

Exploitability

Exploitation is relatively straightforward with no authentication required, though it may need the attacker to be able to send network traffic to the target system's BitLocker service port.

Blast radius

The impact could be severe across Windows environments that use BitLocker encryption, potentially allowing attackers to gain full system access on any vulnerable machine with network connectivity to BitLocker services.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Apply the latest Windows updates including KB5049238 or later, which contain the patched version of BitLocker functionality.
