In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-lib: Avoid division by zero in applyconstraintto_size()
The step variable is initialized to zero. It is changed in the loop, but if it's not changed it will remain zero. Add a variable check before the division.
The observed behavior was introduced by commit 826b5de90c0b ("ALSA: firewire-lib: fix insufficient PCM rule for period/buffer size"), and it is difficult to show that any of the interval parameters will satisfy the sndintervaltest() condition with data from the amdtpratetable[] table.
