CVE-2023-29368

SYSTEM privilege escalation via double free

Published Jun 13, 2023 · Updated Jan 1, 2025

A double-free flaw in Microsoft Windows Filtering Platform allows local users with low privileges to elevate privileges to SYSTEM. The platform releases the same kernel memory twice, but Microsoft has not disclosed the affected function or object's lifetime error. Exploitation requires local code execution; success grants full SYSTEM control, while an unsuccessful attempt can destabilize the host.
