CVE-2026-109938

A flaw was found in FreeRDP. A malicious or compromised Remote Desktop Protocol RDP server can trigger a Denial of Service DoS by sending crafted mapped video geometry updates to a connecting client with video redirection enabled. Due to an integer overflow during coordinate calculations, the...

CVE-2026-109948

A flaw was found in FreeRDP. When a user connects to a malicious Remote Desktop Protocol RDP server with smartcard redirection enabled, the server can issue a crafted smartcard transmission request with an invalid card handle. Because FreeRDP fails to properly clear or restrict the response buffe...

CVE-2026-109677

A flaw was found in FreeRDP. This vulnerability allows information disclosure of client heap memory to a malicious Remote Desktop Protocol RDP server when a user connects to it. Due to improper bounds checking on smartcard pattern byte counts, the server can supply crafted data that triggers...

CVE-2026-111377

A flaw was found in FreeRDP. An authenticated remote attacker can cause a Denial of Service DoS by initiating a message on a static virtual channel and repeatedly sending data fragments without completing the transmission. Because the server fails to enforce cumulative size limits during message...

CVE-2026-111375

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can exploit this issue by sending a specially crafted Remote Applications Integrated Locally RAIL window title update that lacks proper null termination. When the Windows client processes the update, it reads past the...

CVE-2026-111376

A flaw was found in FreeRDP. When handling remote file clipboard transfers on Windows clients, the application fails to properly validate the length of file size responses returned by a Remote Desktop Protocol RDP server. A malicious RDP server can exploit this by returning an abnormally short...

CVE-2026-111382

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can exploit a heap-based out-of-bounds write vulnerability by sending specially crafted display frames to a client during video stream processing. This flaw allows client memory to be corrupted, potentially resulting in...

CVE-2026-111381

A flaw was found in FreeRDP. This flaw allows arbitrary code execution or a Denial of Service DoS when parsing persistent cache files. A local attacker can trigger this vulnerability by tricking a user into loading a maliciously crafted cache file containing oversized image dimensions. This...

CVE-2026-111380

A flaw was found in FreeRDP. When handling audio input on Apple platforms, an integer overflow occurs during buffer size calculations. A malicious Remote Desktop Protocol RDP server can exploit this by sending a specially crafted packet during session setup, causing an undersized memory allocatio...

CVE-2026-111379

A flaw was found in FreeRDP. This vulnerability allows a local attacker to execute arbitrary code or cause a denial of service DoS by supplying a specially crafted persistent cache file. When processing the malformed cache file, an arithmetic calculation error causes an undersized memory buffer t...

CVE-2026-111374

A flaw was found in FreeRDP. This vulnerability allows a malicious Remote Desktop Protocol RDP server to cause a Denial of Service DoS on a connecting client. When camera redirection is enabled, an attacker-controlled server can send stream requests with unadvertised or excessively large dimensio...

CVE-2026-111373

A flaw was found in FreeRDP. A malicious gateway or remote server can trigger a Denial of Service DoS by sending a zero-length WebSocket ping message to a connected client. When processing this empty payload, the application encounters an invalid null memory reference, triggering an assertion...

CVE-2026-111378
