An update that solves three vulnerabilities can now be installed.

Description:

This update for the Linux Kernel 4.4.121-92_92 fixes several issues.

The following security issues were fixed:

• CVE-2019-11477: Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service. (bsc#1137586)
• CVE-2019-11478: Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could use this to cause a denial of service. (bsc#1137586)
• CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network (bsc#1136424).

This update contains a regression fix for CVE-2019-11477 and CVE-2019-11478 (bsc#1140747).
