 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).
