Description

This update for the Linux Kernel 4.4.38-93 fixes several issues.

The following security bug was fixed:

  • CVE-2017-5970: The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a denial of service (system crash) via (1) an application that made crafted system calls or possibly (2) IPv4 traffic with invalid IP options (bsc#1025013).

The following non-security bug was fixed: - Fix for a "Data miscompare on a read" which was observed during the rebuilding of degraded MDRAID VDs. (bsc#1025254)
