freerdp: FreeRDP: heap buffer overflow in server rdpsnd via crafted audio formats

A flaw was found in FreeRDP. An integer wraparound in rdpsndserverselectformat DVIADPCM block-alignment arithmetic bypasses validation in the server-side rdpsnd channel. A malicious RDP client can send crafted SNDCFORMATS PDUs, causing an unbounded heap write during server audio playback that may...

Linux Distros Unpatched Vulnerability : CVE-2026-121963

CVE-2026-121963

FreeRDP before 3.32.2 contains a use-after-free vulnerability in the asynchronous dynamic rdpsnd channel that allows malicious RDP servers to trigger freed callback access by closing the channel with queued audio PDUs. Attackers can send a training PDU then close the channel so the playback threa...

SUSE CVE-2026-121387

FreeRDP 2.0.0 before 3.32.2 contains an out-of-bounds read vulnerability in freerdpdspdecodegsm610 that allows malicious RDP servers to read past audio buffers by sending truncated GSM610 frames. Attackers can negotiate GSM610 on rdpsnd and send a WAVE2 message shorter than a 33- or 32-byte WAV49...
