CVE-2026-22859

freerdp: FreeRDP heap-buffer-overflow (important)

DOCUMENTATION: The CVE program describes this issue as: FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, the URBDRC client does not perform bounds checking on server‑supplied MSUSBINTERFACEDESCRIPTOR values and uses them as indices in libusbudevcompletemsconfigsetup, causing an out‑of‑bounds read. This vulnerability is fixed in 3.20.1. 

            STATEMENT: Red Hat products in their default configuration employ Address Space Layout Randomization (ASLR) which drastically increases the complexity of the successful exploitation of this flaw.

            MITIGATION: 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.
