    CVE-2019-9213

    Summary: Updated kernel packages fix security vulnerability

    Details: This kernel update is based on the upstream 4.14.106 and fixes at least the following security issue: In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (CVE-2019-9213). It also adds a preparatory fix for Skylake systems that will receive a microcode update at a later date to address a TSX errata. WireGuard has been updated to 0.0.20190227. For other uptstream fixes in this update, see the referenced changelogs.
