Description:	Summary: The remote host is missing an update for the 'kernel-linus' package(s) announced via the MGASA-2022-0230 advisory. Vulnerability Insight: This kernel-linus update is based on upstream 5.15.46 and fixes at least the following security issues: KVM: x86/mmu: fix NULL pointer dereference on guest INVPCID (CVE-2022-1789). KVM: x86: avoid calling x86 emulator without a decoded instruction (CVE-2022-1852). A use-after-free vulnerability was found in the Linux kernel's Netfilter subsystem in net/netfilter/nf_tables_api.c. This flaw allows a local attacker with user access to cause a privilege escalation issue (CVE-2022-1966). An out-of-bound write vulnerability was identified within the netfilter subsystem which can be exploited to achieve privilege escalation to root. In order to trigger the issue it requires the ability to create user/net namespaces (CVE-2022-1972). fs/ntfs3: Fix invalid free in log_replay (CVE-2022-1973). For other upstream fixes, see the referenced changelogs. Affected Software/OS: 'kernel-linus' package(s) on Mageia 8. Solution: Please install the updated package(s).
