  <description>This update for the Linux Kernel 4.12.14-197_4 fixes several issues.

The following security issues were fixed:

- CVE-2019-14896: A heap-based buffer overflow vulnerability was found in the 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 (bsc#1157157).
- CVE-2019-14897: A stack-based buffer overflow was found in the  Marvell WiFi chip driver. An attacker was able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA (bsc#1157155).
