CVE-2025-40276

In the Linux kernel, the following vulnerability has been resolved:

drm/panthor: Flush shmem writes before mapping buffers CPU-uncached

The shmem layer zeroes out the new pages using cached mappings, and if
we don’t CPU-flush we might leave dirty cachelines behind, leading to
potential data leaks and/or asynchronous buffer corruption when dirty
cachelines are evicted.
