FKIE_CVE-2022-50285
Vulnerability from fkie_nvd - Published: 2025-09-15 15:15 - Updated: 2026-06-17 05:23
Severity
Summary
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.
