CVE-2022-50285

MEDIUM CVSS: 5.5 Published: 2025-09-15 Modified: 2026-06-17

Description

In the Linux kernel, the following vulnerability has been resolved: mm,hugetlb: take hugetlb_lock before decrementing h->resv_huge_pages The h->*_huge_pages counters are protected by the hugetlb_lock, but alloc_huge_page has a corner case where it can decrement the counter outside of the lock. This could lead to a corrupted value of h->resv_huge_pages, which we have observed on our systems. Take the hugetlb_lock before decrementing h->resv_huge_pages to avoid a potential race.
