CVE-2026-31885 FreeRDP has an out-of-bounds read in ADPCM decoders due to missing predictor/step_index bounds checks

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-bounds read in MS-ADPCM and IMA-ADPCM decoders due to unchecked predictor and stepindex values from input data. This vulnerability is fixed in 3.24.0...

CVE-2026-31884 FreeRDP has a division-by-zero in ADPCM decoders when `nBlockAlign` is 0

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, division by zero in MS-ADPCM and IMA-ADPCM decoders when nBlockAlign is 0, leading to a crash. In libfreerdp/codec/dsp.c, both ADPCM decoders use size % blocksize where blocksize = context-common.format.nBlockAlign...

CVE-2026-31884

CVE-2026-31883

FreeRDP has a size_t underflow in IMA-/MS-ADPCM audio decoders that can trigger a heap-buffer-overflow on the RDPSND channel, caused by subtracting header sizes from a size_t without underflow checks. This affects FreeRDP prior to version 3.24.0 and is fixed in 3.24.0. Related advisories (ALMS/AL...
