Local privilege escalation via use-after-free
Published May 14, 2024 · Updated May 3, 2025
Use-after-free in Microsoft Windows CNG Key Isolation Service allows local users to elevate privileges through a local attack. Microsoft identifies the affected service and weakness but has not disclosed the code locus, freed object, or operation that reuses it. Exploitation requires existing low-privilege access and high-complexity race conditions, with successful execution crossing a security boundary and compromising the system.
