       An update that fixes four vulnerabilities is now available.
    
    Description:
    
       This update for the Linux Kernel 4.4.121-92_104 fixes several issues.
    
       The following security issues were fixed:
    
       - 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#1136446).
       - CVE-2019-11477: A sequence of SACKs may have been crafted by a remote
         attacker such that one can trigger an integer overflow, leading to a
         kernel panic. (bsc#1137586).
       - CVE-2019-11478: It was possible to send a crafted sequence of SACKs
         which would fragment the TCP retransmission queue. A remote attacker may
         have been able to further exploit the fragmented queue to cause an
         expensive linked-list walk for subsequent SACKs received for that same
         TCP connection. (bsc#1137586)
       - CVE-2019-11487: The Linux kernel allowed page->_refcount reference count
         overflow, with resultant use-after-free issues, if about 140 GiB of RAM
         exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,
         include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c,
         mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests
         (bsc#1133191).
