openSUSE Security Update : the Linux Kernel (openSUSE-2019-1085)

high Nessus Plugin ID 123545


The remote openSUSE host is missing a security update.


The openSUSE Leap 42.3 kernel was updated to 4.4.176 to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bnc#1128166).
