An update that solves four vulnerabilities can now be installed.
Description:
This update for the Linux Kernel 4.4.121-92_85 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).
