Summary: Updated kernel packages fix security vulnerabilities

Details: This kernel update provides the upstream 4.14.121. It adds additional fixes to the kernel side mitigations for the Microarchitectural Data Sampling (MDS, also called ZombieLoad attack) vulnerabilities. It also fixes the following security issues: A flaw was found in the Linux kernel's freescale hypervisor manager implementation. A parameter passed via to an ioctl was incorrectly validated and used in size calculations for the page size calculation. An attacker can use this flaw to crash the system or corrupt memory or, possibly, create other adverse security affects (CVE-2019-10142). fs/ext4/extents.c in the Linux kernel through 5.1.2 does not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem (CVE-2019-11833). It also fixes an upstream regression that caused older 'legacy' bluetooth adapters to stop working (mga #24840). For other uptstream fixes in this update, see the referenced changelogs.
