CVE-2026-109946

FreeRDP 3.11.0 before 3.32.0 does not validate that AVC444 and AVC444v2 region widths are even before YUV444 conversion, so an odd width reaches an assertion and aborts the client. A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by...

CVE-2026-109945

FreeRDP versions 3.0.0 before 3.32.0 are vulnerable to a heap use-after-free vulnerability within the smartcard emulation component. The root cause is a race condition where the SCARD_IOCTL_DISCONNECT and SCARD_IOCTL_TRANSMIT operations occur concurrently on a single card handle. A malicious RDP ...

CVE-2026-109946 FreeRDP 3.11.0 before 3.32.0 Reachable Assertion via AVC444 Odd Region Width

FreeRDP 3.11.0 before 3.32.0 does not validate that AVC444 and AVC444v2 region widths are even before YUV444 conversion, so an odd width reaches an assertion and aborts the client. A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by...

CVE-2026-109946 FreeRDP 3.11.0 before 3.32.0 Reachable Assertion via AVC444 Odd Region Width

FreeRDP 3.11.0 before 3.32.0 does not validate that AVC444 and AVC444v2 region widths are even before YUV444 conversion, so an odd width reaches an assertion and aborts the client. A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by...

CVE-2026-109946

The FreeRDP client versions 3.11.0 before 3.32.0 are vulnerable to a reachable assertion (CWE-617) during YUV444 conversion. The software fails to validate that AVC444 and AVC444v2 region widths are even numbers. A malicious or compromised RDP server can trigger a client crash by sending an in-bo...

CVE-2026-109945 FreeRDP 3.0.0 before 3.32.0 Smartcard Use-After-Free via Concurrent Disconnect and Transmit

FreeRDP 3.0.0 before 3.32.0 contains a heap use-after-free vulnerability in smartcard emulation when SCARDIOCTLDISCONNECT and SCARDIOCTLTRANSMIT operate concurrently on one card handle. A malicious RDP server can overlap these IRPs through separate context workers to free and reuse the SCardHandl...
