CVE-2026-57157

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. FreeRDP server implementations with the MS-RDPECAM camera device enumerator channel enabled are vulnerable to an out-of-bounds heap read. A malicious RDP client can exploit this by manipulating the DeviceName a...

CVE-2026-57156

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0 on 32-bit builds, FreeRDP clients contain an integer overflow in updatereaddeltapoints in libfreerdp/core/orders.c when multiplying an attacker-controlled point count by sizeofDELTAPOINT, allowing a malicious RDP pee...

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 planar_decompress_plane_rle_only: heap OOB read — incomplete fix for CVE-2026-23530

FreeRDP is a free implementation of the Remote Desktop Protocol. From 3.21.0 before 3.28.0, FreeRDP clients using the GFX pipeline contain an incomplete fix for CVE-2026-23530 in planardecompressplanerleonly in libfreerdp/codec/planar.c, allowing a malicious RDP server to send a truncated...

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...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, a malicious RDP server could cause the FreeRDP client to crash by sending audio data in IMA ADPCM format with an invalid initial step index value = 89. The invalid step index was read directly from the netwo...

CVE-2026-40033

A flaw was found in FreeRDP.If a user connects to a malicious Remote Desktop RDP server, a security flaw in FreeRDP could cause the application to crash or allow the server to run unauthorized code on the user's system. Mitigation To mitigate this issue, users should avoid connecting to untrusted...

ROS-20260611-73-0034

The vulnerability of the ecamchannelwrite function in the FreeRDP remote desktop protocol is related to the use of memory after it is freed. Exploiting this vulnerability could allow a malicious actor to cause a service failure...

UBUNTU-CVE-2026-45700

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, FreeRDP's planar bitmap decoder has an out-of-bounds heap write when decoding RLE planar data. In libfreerdp/codec/planar.c, freerdpbitmapdecompressplanar validates the X destination coordinate nXDst against the...

UBUNTU-CVE-2026-44420

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, a malicious RDP client can trigger a heap-buffer-overflow write in FreeRDP's server-side clipboard cliprdr channel by sending a CBCLIPCAPS PDU with a too-small capabilitySetLength. This can crash the server process...

UBUNTU-CVE-2026-44421

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, a malicious RDP server can trigger a heap-buffer-overflow write in the FreeRDP client by sending crafted RDPGFX PDUs.
