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: drm/panthor: Lock XArray when getting entries for the VM Similar to commit cac075706f29 ("drm/panthor: Fix race when converting group handle to group object") we need to use the XArray's internal locking when retrieving a vm pointer from there. v2: Removed part of the patch that was trying to protect fetching the heap pointer from XArray, as that operation is protected by the @pool->lock.

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.

dbcve analysis
How this class of weakness works · CWE-667

Shared resources are accessed without correct locking, so concurrent operations interleave into inconsistent — and sometimes exploitable — states, or deadlock the service outright. These bugs are subtle and timing-dependent. The fix is correct, consistent locking or atomic operations around every shared resource.

Recommended fix High confidence

Linux Kernel 6.11.8 or later, or 6.12.1 or later

  1. Obtain the patch from commit 3342f066a8e1020a6f7d1fbd6b23bfdeda473eb5: https://git.kernel.org/stable/c/3342f066a8e1020a6f7d1fbd6b23bfdeda473eb5
  2. Apply the patch to the Linux kernel source tree, specifically targeting drivers/gpu/drm/panthor/panthor_vm.c
  3. Ensure the XArray locking is properly implemented when retrieving vm pointers from the XArray, following the pattern in commit cac075706f29
  4. Rebuild the kernel with the patched drivers/gpu/drm/panthor/ module
  5. Reboot or reload the panthor kernel module to load the fixed code
Caveat Kernel recompilation required; if using distribution kernels, wait for vendor-provided update
