What is CVE-2026-110829?

FreeRDP versions prior to 3.32.0 are susceptible to a null pointer dereference issue in the rdpsnd channel. This arises when a fragment signals CHANNEL_FLAG_LAST without first indicating CHANNEL_FLAG_FIRST. A malicious Remote Desktop Protocol (RDP) server may exploit this flaw by sending a malformed rdpsnd Protocol Data Unit (PDU) on a new channel, leading to a crash of the FreeRDP client and resulting in a denial of service.

Affected Version(s)

FreeRDP 3.0.0 < 3.32.0

FreeRDP 3.32.0
