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: thermal: core: Reference count the zone in thermal_zone_get_by_id() There are places in the thermal netlink code where nothing prevents the thermal zone object from going away while being accessed after it has been returned by thermal_zone_get_by_id(). To address this, make thermal_zone_get_by_id() get a reference on the thermal zone device object to be returned with the help of get_device(), under thermal_list_lock, and adjust all of its callers to this change with the help of the cleanup.h infrastructure.

Vendor patch git.kernel.org →
Recommended fix High confidence

Linux Kernel 6.11.4 or later (or 6.13+ if currently on 6.12)

  1. 1. Identify the current running kernel version using `uname -r`
  2. 2. Check if the version is affected: versions < 6.11.4 or exactly 6.12
  3. 3. If affected, upgrade the Linux kernel to version 6.11.4 or later (for versions < 6.11.4), or to version 6.13 or later (if currently on 6.12)
  4. 4. Update bootloader configuration if necessary to ensure the new kernel boots
  5. 5. Reboot the system to load the patched kernel
  6. 6. Verify the fix is applied by checking the kernel version with `uname -r` and confirming it shows 6.11.4 or later, or 6.13+ if originally on 6.12
Caveat Kernel upgrades may require rebuilding out-of-tree kernel modules; ensure compatible drivers are available before upgrading
