CVE-2026-23883 - Heap-use-after-free in update_pointer_new
CVE ID : CVE-2026-23883
Published : Jan. 19, 2026, 6:16 p.m. | 42 minutes ago
Description : FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, `xf_Pointer_New` frees `cursorPixels` on failure, then `pointer_free` calls `xf_Pointer_Free` and frees it again, triggering ASan UAF. A malicious server can trigger a client‑side use after free, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.
Severity: 7.7 | HIGH
