Mageia 2020: 0073 Moderate: Kernel Security Vulnerabilities Update

This update is based on upstream 5.4.17 and fixes atleast the following security vulnerabilities:
In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel may be able to read memory locations from another process in the same guest. This problem is limit to the host running linux kernel 4.10 with a guest running linux kernel 4.16 or later. The problem mainly affects AMD processors but Intel CPUs cannot be ruled out (CVE-2019-3016).
A heap-based buffer overflow vulnerability was found in the Linux kernel, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP (CVE-2019-14896).
