CVE-2026-121407

A flaw was found in FreeRDP. An authenticated remote attacker can cause a Denial of Service DoS by sending a specially crafted message to the shadow server's remdesk virtual channel. Due to an inverted packet length verification check, processing the malformed data triggers an internal assertion...

CVE-2026-121407

FreeRDP before 3.32.2 contains a denial of service vulnerability in the shadow server's remdeskserverthread that allows authenticated clients to crash the process via an inverted PDU length check.
