CVE-2025-40218

CVE-2025-40218: In the Linux kernel, DAMON’s vaddr implementation was retrying pte_offset_map_lock() on failure, which could loop in scenarios where the target is a PMD migration entry, potentially causing a soft lockup when DAMON runs in parallel with CPU hotplug. The fix removes the retry-on-fa...
