Oracle Linux 7 / 8 : Unbreakable Enterprise kernel-container (ELSA-2022-9265)

high Nessus Plugin ID 159609

Language:

Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 7 / 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2022-9265 advisory.

 - 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. (CVE-2022-1158)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel-uek-container and / or kernel-uek-container-debug packages.
