An update that solves five vulnerabilities and has five security fixes can now be installed.

Description:

The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2020-14314: Fixed a potential negative array index in do_split() (bsc#1173798).
• CVE-2020-14331: Fixed a missing check in vgacon scrollback handling (bsc#1174205).
• CVE-2020-16166: Fixed a potential issue which could have allowed remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG (bsc#1174757).
• CVE-2019-16746: Fixed an improper check of the length of variable elements in a beacon head, leading to a buffer overflow (bsc#1152107).
• CVE-2020-14386: Fixed a potential local privilege escalation via memory corruption (bsc#1176069).

The following non-security bugs were fixed:

• bonding: fix active-backup failover for current ARP slave (bsc#1174771).
• Drivers: hv: vmbus: Only notify Hyper-V for die events that are oops (bsc#1175127).
• ibmvnic: Fix IRQ mapping disposal in error path (bsc#1175112 ltc#187459).
• mm, vmstat: reduce zone->lock holding time by /proc/pagetypeinfo (bsc#1175691).
• ocfs2: add trimfs dlm lock resource (bsc#1175228).
• ocfs2: add trimfs lock to avoid duplicated trims in cluster (bsc#1175228).
