CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2022-49991
Medium (5.5) in linux linux kernel. EPSS 0.3% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb: avoid corrupting page->mapping in hugetlb_mcopy_atomic_pte
In MCOPY_ATOMIC_CONTINUE case with a non-shared VMA, pages in the page
cache are installed in the ptes. But hugepage_add_new_anon_rmap is called
for them mistakenly because they're not vm_shared. This will corrupt the
page->mapping used by page cache code.
