Severity CVSS v4.0:
Pending analysis
Type:
CWE-369 Divide By Zero
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: firewire-lib: Avoid division by zero in apply_constraint_to_size()<br /> <br /> The step variable is initialized to zero. It is changed in the loop,<br /> but if it&amp;#39;s not changed it will remain zero. Add a variable check<br /> before the division.<br /> <br /> The observed behavior was introduced by commit 826b5de90c0b<br /> ("ALSA: firewire-lib: fix insufficient PCM rule for period/buffer size"),<br /> and it is difficult to show that any of the interval parameters will<br /> satisfy the snd_interval_test() condition with data from the<br /> amdtp_rate_table[] table.<br /> <br /> Found by Linux Verification Center (linuxtesting.org) with SVACE.
