Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for the Linux Kernel 4.4.180-94_100 fixes several issues.

The following security issues were fixed :

CVE-2020-10757: Fixed an issue where remaping hugepage DAX to anon mmap could have caused user PTE access (bsc#1172437).

CVE-2019-15666: Fixed an out of bounds read __xfrm_policy_unlink, which could have led to denial of service (bsc#1172140).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
