CVE-2026-109942

FreeRDP 2.3.0 before 3.32.0 dereferences a NULL stream in rdgprocessclosepacket in libfreerdp/core/gateway/rdg.c because rdgprocesscontrolpacket accepts a header-only PKTTYPECLOSECHANNEL packet and passes the null payload without a check. A malicious or compromised RD Gateway can send an eight-by...

CVE-2026-109943

FreeRDP 3.29.0 before 3.32.0 contains a double free in the client's async-update message proxy, which shallow-copies the parser-owned PolygonSC or PolygonCB points array when numPoints is zero, so both the queue consumer and parser cleanup free it. A malicious RDP server can send a point-bearing...
