What to do
AI-suggested
A fix has been implemented in the Linux kernel to remove the unsafe call to set_page_dirty_lock(). Users should apply the official kernel updates containing this fix when available. Since this is a kernel-level issue, upgrading to a patched kernel version is the recommended remediation.
Description
CVE-2025-37978 is a medium severity vulnerability in the Linux kernel's block integrity subsystem. It involves improper use of the set_page_dirty_lock() function, which cannot be called from interrupt context. This flaw could cause kernel oops (crashes) when multiple protection information buffers share the same page. The issue was resolved by removing the call to set_page_dirty_lock() and adjusting related function arguments.
