CVE-2022-1158 (GCVE-0-2022-1158)

Vulnerability from cvelistv5 – Published: 2022-08-05 00:00 – Updated: 2024-08-02 23:55
VLAI?
Summary
A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition.
Severity ?
