Code execution via Geolocation Service double free
Published Jun 13, 2023 · Updated Jan 1, 2025
A double-free flaw in Microsoft Windows Geolocation Service allows context-dependent attackers to execute code after user interaction. Within the Geolocation Service, an allocation is released twice while processing attacker-controlled input; Microsoft does not disclose the affected routine or input format. Exploitation requires a local attack path and user interaction, and successful exploitation executes code in the victim's security context.
