FKIE_CVE-2022-50285

Vulnerability from fkie_nvd - Published: 2025-09-15 15:15 - Updated: 2025-12-04 18:54

Severity ?

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

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.
