Linux Kernel Integrity Vulnerability Impacting Multiple Protection Buffers

CVE-2025-37978

What is CVE-2025-37978?

A vulnerability identified in the Linux kernel relates to the improper handling of multiple protection information buffers within the same page. The specific flaw arises from invoking set_page_dirty_lock() in an interrupt context, which can lead to system instability and errors. This issue highlights the need for careful management of page states, especially as protection information buffers do not have an associated file to synchronize page dirtiness. The recent resolution removes the problematic function call, ensuring stable operation by preventing potential oopses in affected systems.
