CVE-2026-57157 Out-of-bounds read in the camera device enumerator server (rdpecam) via unterminated DeviceName / VirtualChannelName

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, FreeRDP server implementations with the MS-RDPECAM camera device enumerator channel enabled scan attacker-supplied DeviceName and VirtualChannelName fields for a NUL terminator in...

CVE-2026-57158

FreeRDP (Remote Desktop Protocol client) is affected in versions 3.21.0 through 3.27.x where the GFX pipeline’s planar_decompress_plane_rle_only fix is incomplete, allowing a malicious RDP server to send a truncated RDPGFX_CMDID_WIRETOSURFACE_1 planar payload that may read one byte past the input...

CVE-2026-55827 FreeRDP: Heap out-of-bounds write in RemoteFX (RFX) Cache Bitmap V3 decode

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.1, FreeRDP clients launched with the non-default /cache:codec:rfx option pass desktop stride and height to RemoteFX decoding for Cache Bitmap V3 data while allocating bitmap-data only for the smaller DstWidth and...

PT-2026-57293

Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 3.28.0 Description FreeRDP clients on 32-bit builds contain an integer overflow in the update read delta points function within libfreerdp/core/orders.c. This occurs when multiplying an attacker-controlled point count...

UBUNTU-CVE-2026-56297

FreeRDP before 3.22.0 contains a use-after-free vulnerability in dvcmanchannelclose and dvcmancallonreceive due to improper synchronization of channelcallback access. A malicious RDP server can trigger a race condition by sending DYNVCDATA and DYNVCCLOSE messages concurrently, causing...

freerdp: FreeRDP: Out-of-bounds write in planar bitmap decoder allows arbitrary code execution

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. The planar bitmap decoder contains an out-of-bounds heap write vulnerability when processing RLE planar data. A remote attacker could exploit this by providing specially crafted RLE planar data, leading to an...
