CVE-2026-91960

FreeRDP versions before 3.31.0 contain an integer overflow in WinPR's Stream_EnsureRemainingCapacity function. A malicious RD Gateway peer can send a WebSocket Ping frame with a crafted 64-bit extended payload length, triggering integer wraparound that leads to a double free and crashes the FreeR...

CVE-2026-91960 FreeRDP before 3.31.0 Integer Overflow Double Free

FreeRDP versions before 3.31.0 contain an integer overflow in WinPR's StreamEnsureRemainingCapacity function that allows remote attackers to cause denial of service. A malicious RD Gateway peer can send a WebSocket Ping frame with a crafted 64-bit extended payload length to trigger integer...

CVE-2026-91959

FreeRDP before 3.31.0 contains a buffer over-read in the rts_read_result function within the RPC gateway transport parser . The root cause is that the function length-checks 2 bytes but then reads 4 , allowing a remote attacker to send a malicious BIND_ACK PDU with a truncated result entry to tri...

CVE-2026-91956 FreeRDP before 3.31.0 Out-of-Bounds Read via URBDRC

FreeRDP before 3.31.0 contains an out-of-bounds read vulnerability in the URBDRC channel's funcgetepdesc function that indexes interface arrays by position instead of protocol field InterfaceNumber. A malicious RDP server can send a crafted SELECTCONFIGURATION message with permuted InterfaceNumbe...

CVE-2026-91956

FreeRDP before 3.31.0 contains an out-of-bounds read vulnerability in the URBDRC (USB device redirection) channel's func_get_ep_desc function. The root cause is an index mismatch : the function indexes interface arrays by position rather than by the protocol field InterfaceNumber. A malicious RDP...
