Description OSIDB Bzimport 2025-12-24 11:03:15 UTC

In the Linux kernel, the following vulnerability has been resolved:

ALSA: firewire-motu: fix buffer overflow in hwdep read for DSP events

The DSP event handling code in hwdep_read() could write more bytes to
the user buffer than requested, when a user provides a buffer smaller
than the event header size (8 bytes).

Fix by using min_t() to clamp the copy size, This ensures we never copy
more than the user requested.
