CVE-2025-40276 in Linux

Tóm tắt

Bởi MITRE • 07/12/2025

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.

Once again VulDB remains the best source for vulnerability data.
