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: firmware: cs_dsp: Prevent buffer overrun when processing V2 alg headers Check that all fields of a V2 algorithm header fit into the available firmware data buffer. The wmfw V2 format introduced variable-length strings in the algorithm block header. This means the overall header length is variable, and the position of most fields varies depending on the length of the string fields. Each field must be checked to ensure that it does not overflow the firmware data buffer. As this ia bugfix patch, the fixes avoid making any significant change to the existing code. This makes it easier to review and less likely to introduce new bugs.

How this class of weakness works · CWE-120

A fixed-size buffer is filled without checking the length of the incoming data, so it overflows into neighbouring memory. This is the classic overflow attackers use to overwrite return addresses and hijack execution. The fix is strict length checks and safe, bounded string and memory functions.

Recommended fix High confidence

6.1.100+ or 6.6.41+ or 6.9.10+ (depending on which branch you are on)

  1. 1. Identify the current kernel version using 'uname -r' or 'cat /proc/version'
  2. 2. Determine the appropriate upgrade path based on your current version and distribution: For 5.16+ to 6.1.x, upgrade to 6.1.100 or later; For 6.2+ to 6.6.x, upgrade to 6.6.41 or later; For 6.7+ to 6.9.x, upgrade to 6.9.10 or later
  3. 3. For Debian/Ubuntu: Run 'apt update && apt upgrade' or install the specific linux-image package for your desired stable release
  4. 4. For RHEL/CentOS/Fedora: Run 'yum update' or 'dnf update' to receive the stable kernel package
  5. 5. For other distributions: Obtain the kernel source from https://www.kernel.org/ and apply the patch from commit 014239b9971d79421a0ba652579e1ca1b7b57b6d, then compile
  6. 6. Reboot the system into the new kernel version
  7. 7. Verify the fix is applied by checking the kernel version and confirming cs_dsp module loads correctly
Caveat Kernel upgrades may require reboot and could introduce compatibility issues with proprietary kernel modules or specific hardware drivers; ensure backups and test in non-production environment first
