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: netfilter: nf_tables: discard table flag update with pending basechain deletion Hook unregistration is deferred to the commit phase, same occurs with hook updates triggered by the table dormant flag. When both commands are combined, this results in deleting a basechain while leaving its hook still registered in the core.

Recommended fix High confidence

Linux Kernel 5.4.274, 5.10.215, 5.15.155, or 6.1.86 (or later stable releases); Debian 10 users should upgrade to a newer Debian release (11+) with a fixed kernel or use a Debian LTS kernel from https://wiki.debian.org/LTS

  1. Identify the current kernel version using `uname -r`
  2. For Debian 10 (Buster), upgrade to a kernel version that includes the fix: 5.4.274+ (for 5.4.x), 5.10.215+ (for 5.10.x), 5.15.155+ (for 5.15.x), or 6.1.86+ (for 6.1.x)
  3. On Debian systems, update package lists with `apt-get update` and install the new kernel via `apt-get install linux-image-<version>`
  4. Reboot into the updated kernel using `reboot`
  5. Verify the fix is applied by checking the kernel version and confirming the nf_tables patch is included: `uname -r` and check kernel changelog
Caveat Kernel upgrades may require system reboot and could introduce compatibility issues with custom kernel modules or specific hardware drivers; ensure critical applications are tested against the new kernel
