Description

A flaw was found in FreeRDP. An incomplete fix for a heap-use-after-free vulnerability (CVE-2026-24680) in the SDL2 implementation allows a remote attacker to trigger a denial of service. The pointer is not nulled after being freed, which can lead to memory corruption. This issue means that environments still using SDL2 may remain vulnerable despite the previous advisory.
