CVE-2026-79978 Out-of-bounds write in the ADXL345 sensor driver RTIO streaming FIFO read path

The RTIO streaming completion callback adxl345processfifosamplescb in drivers/sensor/adi/adxl345/adxl345stream.c clamps the amount of FIFO data it will report readlen = MINfifobytes, bufavail to the space actually returned by rtiosqerxbuf, but then queues one 6-byte bus read per hardware FIFO ent...

CVE-2026-79978

The ADXL345 sensor driver in Zephyr contains an out-of-bounds write vulnerability in the adxl345_process_fifo_samples_cb() callback within drivers/sensor/adi/adxl345/adxl345_stream.c. The root cause is that the driver calculates buffer offsets based on hardware-reported FIFO entries rather than t...
