CBL Mariner 2.0 Security Update: kernel (CVE-2022-0171)

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-0171 advisory. - A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root hos...

Important: kernel

Issue Overview: AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on AMD instances 5a. This is done by default, and no administrator action is...
