CVE-2026-114045

FreeRDP before 3.32.1 contains a heap-based buffer overflow in the server-side rdpsnd channel because an integer wraparound in rdpsndserverselectformat DVIADPCM block-alignment arithmetic bypasses validation. A malicious RDP client can send two SNDCFORMATS PDUs with an nBlockAlign too small for...

CVE-2026-114045 FreeRDP before 3.32.1 Heap Buffer Overflow via rdpsnd_server_select_format

FreeRDP before 3.32.1 contains a heap-based buffer overflow in the server-side rdpsnd channel because an integer wraparound in rdpsndserverselectformat DVIADPCM block-alignment arithmetic bypasses validation. A malicious RDP client can send two SNDCFORMATS PDUs with an nBlockAlign too small for...

CVE-2026-114045

FreeRDP versions prior to 3.32.1 are vulnerable to a heap-based buffer overflow in the server-side rdpsnd channel . The root cause is an integer wraparound within the rdpsnd_server_select_format() function during DVI_ADPCM block-alignment arithmetic, which allows validation to be bypassed. A mali...

CVE-2026-110829

FreeRDP versions from 3.0.0 before 3.32.0 contain a null pointer dereference in the rdpsnd channel when a fragment sets CHANNELFLAGLAST without CHANNELFLAGFIRST. A malicious RDP server can send a malformed rdpsnd PDU on a fresh channel to crash the client and cause denial of service...

CVE-2026-110829

FreeRDP versions 3.0.0 through 3.31.x are vulnerable to a null pointer dereference within the rdpsnd channel .
