Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire-lib: Avoid division by zero in apply_constraint_to_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 snd_interval_test() condition with data from the amdtp_rate_table[] table. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

Linux kernel 5.4.285, 5.10.229, 5.15.170, or 6.1.115 (depending on your current branch)

  1. Identify the current kernel version using 'uname -r' or 'cat /proc/version'
  2. Determine which kernel branch you are running (e.g., 5.4.x, 5.10.x, 5.15.x, or 6.1.x) from the version number
  3. Upgrade the Linux kernel to a fixed version: For 5.4.x branch, upgrade to 5.4.285 or later; For 5.10.x branch, upgrade to 5.10.229 or later; For 5.15.x branch, upgrade to 5.15.170 or later; For 6.1.x branch, upgrade to 6.1.115 or later
  4. Use your distribution's package manager to install the updated kernel (e.g., 'apt-get update && apt-get upgrade' for Debian/Ubuntu, 'yum update' for RHEL/CentOS, or 'dnf update' for Fedora)
  5. Reboot the system to load the new kernel
  6. Verify the new kernel version is running with 'uname -r'
Caveat Kernel upgrades may require rebooting services; ensure applications and drivers are compatible with the new kernel version before production deployment
