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: octeontx2-pf: Fix transmit scheduler resource leak Inorder to support shaping and scheduling, Upon class creation Netdev driver allocates trasmit schedulers. The previous patch which added support for Round robin scheduling has a bug due to which driver is not freeing transmit schedulers post class deletion. This patch fixes the same.

Recommended fix High confidence

Linux kernel 6.6.28+ (for 6.6.x), 6.8.7+ (for 6.7.x-6.8.x), or latest 6.9.x stable

  1. 1. Identify the current running Linux kernel version using `uname -r`
  2. 2. Determine if the system uses the octeontx2-pf driver (Cavium Octeon TX2 network driver) by checking kernel config or module list
  3. 3. Plan a kernel upgrade to a fixed stable release: upgrade to kernel 6.6.28 or later, 6.8.7 or later, or 6.9.x (latest available)
  4. 4. Before upgrading, back up critical data and verify hardware compatibility with the new kernel
  5. 5. Apply the upgrade through the distribution's package manager (e.g., `apt update && apt upgrade` for Debian/Ubuntu, `yum update` for RHEL/CentOS, or `zypper update` for SUSE)
  6. 6. After reboot, verify the fix is applied by checking `dmesg` for any related error messages and confirming the kernel version with `uname -r`
Caveat Kernel upgrades may introduce regressions or require rebuilding third-party kernel modules. Ensure all proprietary drivers (like GPU drivers) are compatible with the new kernel version before upgrading.
