About this tag
The firewire-motu tag on WindowsForum.com covers discussions about the ALSA FireWire Motu driver, which supports MOTU and similar FireWire audio interfaces on Linux. Recent threads focus on two CVEs (CVE-2025-68753 and CVE-2025-68347) that were patched in the Linux kernel. These vulnerabilities involved memory handling bugs in the driver's copy loops and DSP event handling, where improper bounds checking could allow writing beyond user buffers. The fixes added bounds checks and clamped copy lengths to prevent overflows. While the tag is Linux-specific, it may interest Windows users who run Linux in virtual machines or dual-boot setups for audio production, as the driver is part of the ALSA sound architecture.

    CVE-2025-68753: ALSA FireWire Motu Driver Bounds Check Patch

    The Linux kernel has been assigned CVE-2025-68753 for a vulnerability in the ALSA firewire-motu driver where a flawed copy loop using put_user could write beyond a user buffer when the buffer size is not aligned to 4 bytes; upstream developers patched the driver by adding a bounds check and...

    Linux Kernel CVE-2025-68347: ALSA FireWire Motu Driver Copy Clamp Fix

    The Linux kernel received a focused fix for a small but consequential memory‑handling bug in the ALSA firewire-motu driver that could let the driver write more bytes to userspace than requested during DSP event handling — tracked as CVE-2025-68347 and remedied upstream by clamping copy length...
