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: bnxt: Do not read past the end of test names Test names were being concatenated based on a offset beyond the end of the first name, which tripped the buffer overflow detection logic: detected buffer overflow in strnlen [...] Call Trace: bnxt_ethtool_init.cold+0x18/0x18 Refactor struct hwrm_selftest_qlist_output to use an actual array, and adjust the concatenation to use snprintf() rather than a series of strncat() calls.

Recommended fix High confidence

Kernel 6.1.9 or later, or 6.2.1 or later

  1. Identify the currently running kernel version using `uname -r`
  2. Check if the system is running a kernel version in the affected range: >= 4.12 and < 6.1.9, or exactly 6.2
  3. Schedule a maintenance window for the kernel upgrade
  4. Upgrade the Linux kernel package to version 6.1.9 or later, or 6.2.1 or later using your distribution's package manager (e.g., `apt-get update && apt-get install linux-image-<version>` for Debian/Ubuntu, or `yum update kernel` for RHEL/CentOS)
  5. Reboot the system to load the patched kernel
  6. Verify the new kernel version is running using `uname -r` and confirm it is 6.1.9+ or 6.2.1+
Caveat Minor risk: kernel upgrades may include driver changes; verify bnxt network driver loads correctly after reboot
