CVE-2024-50066

CVE-2024-50066 is a Linux kernel race in mm/mremap where move_page_tables can race with retract_page_tables under THP/rmap locking. The flaw stems from reading the PMD type before acquiring rmap locks, potentially creating bogus PMD entries (e.g., mapping page 0 as a page table on x86) and enabli...
