FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, the fix for the heap-use-after-free described in CVE-2026-24680 is incomplete. While the vulnerable execution flow referenced in the advisory exists in the SDL2 implementation, the fix appears to have been applied only to the SDL3 code path. In the SDL2 implementation, the pointer is not nulled after free. This creates a situation where the advisory suggests the vulnerability is fully resolved, while builds or environments still using SDL2 may retain the vulnerable logic. A complete fix is available in version 3.23.0.
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.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
