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: clk: sunxi-ng: h6: Reparent CPUX during PLL CPUX rate change While PLL CPUX clock rate change when CPU is running from it works in vast majority of cases, now and then it causes instability. This leads to system crashes and other undefined behaviour. After a lot of testing (30+ hours) while also doing a lot of frequency switches, we can't observe any instability issues anymore when doing reparenting to stable clock like 24 MHz oscillator.

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 5.4.276+ / 5.10.217+ / 5.15.159+ / 6.1.91+ (or Debian 11/12 with patched kernel)

  1. For Linux Kernel: Upgrade to a patched version: 5.4.276+, 5.10.217+, 5.15.159+, or 6.1.91+ depending on your current branch
  2. For Debian 10 (Buster): Note that Debian 10 is end-of-life. Consider upgrading to Debian 11 (LTS) or Debian 12, which include patched kernels
  3. If running a distribution kernel, use your package manager to update (e.g., apt-get update && apt-get upgrade linux-image-arm64 or similar)
  4. If running a custom kernel, apply the commit 0b82eb134d2942ecc669e2ab2be3f0a58d79428a or a subsequent fix and rebuild
  5. After upgrade, verify the kernel version matches or exceeds one of the fixed versions listed above
Caveat Kernel upgrades may require system reboot and could have compatibility implications with custom modules or specific hardware configurations
