These calculations can create an issue where the kernel memory allocator will not allocate the correct count of pages yet expect them to be usable. This can lead to the ftrace() output to appear to corrupt kernel memory and possibly be used for privileged escalation or more likely kernel panic.(CVE-2016-9754) - A flaw was found in the Linux kernel last seen 2020-06-12 modified 2019-05-13 plugin id 124821 published 2019-05-13 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/124821 title EulerOS Virtualization 3.0.1.0 : kernel (EulerOS-SA-2019-1498) NASL family SuSE Local Security Checks NASL id SUSE_SU-2017-0268-1.NASL description This update for the Linux Kernel 3.12.51-52_39 fixes several issues.
