A flaw was found in the Linux kernel's ALSA (Advanced Linux Sound Architecture) subsystem, specifically within the 6fire driver. This vulnerability allows a malicious USB device to trigger an out-of-bounds read by sending a specially crafted MIDI event with an excessive length. This can lead to the disclosure of sensitive information from kernel memory. The issue can be triggered upon device connection without requiring user interaction, provided a MIDI input substream is open.
kernel: ALSA: 6fire: bound the MIDI event length from the device — rated Moderate by Red Hat. Released 2026-09-11, updated 2026-10-25.
