What is CVE-2025-40276?

A vulnerability exists in the Linux kernel's DRM subsystem, specifically within the shmem layer, where new pages are zeroed out using cached mappings. Failure to execute a CPU flush may leave dirty cachelines unaddressed, potentially resulting in harmful data leaks and the risk of asynchronous buffer corruption upon eviction of these cachelines. This vulnerability highlights the critical need for proper handling of memory management operations to ensure data integrity and system stability.
