high Nessus Plugin ID 170977

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0229-1 advisory.

- A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171) (CVE-2022-2602)

- A use-after-free flaw was found in the Linux kernel's SGI GRU driver in the way the first gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-3424)

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

Solution

Update the affected kernel-livepatch-5_3_18-150200_24_115-default, kernel-livepatch-5_3_18-150200_24_126-default and / or kernel-livepatch-5_3_18-150200_24_129-default packages.
