CVE-2024-57883
The CVE CVE-2024-57883 is a Linux kernel vulnerability in mm/hugetlb: independent PMD page table shared count. The root cause is an incorrect refcount increment in try_get_folio() that can be triggered by callers such as split_huge_pages, leading to a leaked PMD page table when the refcount is in...

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...
Linux Kernel Race Condition Vulnerabilities
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a race condition between movenormalpmd and extractpagetables in the mremap function, which could lead to...
