Publication date: 19 Nov 2019
URL: https://advisories.mageia.org/MGASA-2019-0332.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2019-0155,
     CVE-2019-11135,
     CVE-2018-12207

This kernel update is based on the upstream 5.3.13 and fixes atleast the 
following security issues:

Insufficient access control in a subsystem for Intel (R) processor graphics
may allow an authenticated user to potentially enable escalation of
privilege via local access (CVE-2019-0155).

TSX Asynchronous Abort condition on some CPUs utilizing speculative
execution may allow an authenticated user to potentially enable
information disclosure via a side channel with local access
(CVE-2019-11135).

Improper invalidation for page table updates by a virtual guest operating
system for multiple Intel(R) Processors may allow an authenticated user to
potentially enable denial of service of the host system via local access
(CVE-2018-12207). 

For proper mitigations and fixes for theese issues, a microcode update is
also needed, either with a bios/uefi update from your hardware vendor or
by installing the microcode-0.20191112-1.mga7.nonfree update (mga#25688).

For other upstream fixes in this update, see the referenced changelogs.
