LOW 3.6
CVE-2026-79978 is a low-severity flaw (CVSS 3.6) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The RTIO streaming completion callback adxl345_process_fifo_samples_cb() in drivers/sensor/adi/adxl345/adxl345_stream.c clamps the amount of FIFO data it will report (read_len = MIN(fifo_bytes, buf_avail)) to the space actually returned by rtio_sqe_rx_buf(), but then queues one 6-byte bus read per hardware FIFO entry at consecutive offsets from read_buf, bounded by the device-reported entry count rather than by the clamp. When the allocated buffe
