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).
