(CVE-2017-15121) - A flaw was found in the Linux kernel's handling of fork failure when dealing with event messages in the userfaultfd code. Failure to fork correctly can create a fork event that will be removed from an already freed list of events. (CVE-2017-15126) - An out-of-bounds write vulnerability was found in the Linux kernel's vmw_surface_define_ioctl() function, in the 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-7294) - A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor implements its device control API. While creating a device via kvm_ioctl_create_device(), the device holds a reference to a VM object, later this reference is transferred to the caller's file descriptor table. If such file descriptor was to be closed, reference count to the VM object could become zero, potentially leading to a use- after-free issue. A user/process could use this flaw to crash the guest VM resulting in a denial of service issue or, potentially, gain privileged access to a system. (CVE-2019-6974) - A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor emulates a preemption timer for L2 guests when nested (=1) virtualization is enabled. This high resolution timer(hrtimer) runs when a L2 guest is active. After VM exit, the sync_vmcs12() timer object is stopped. The use-after-free occurs if the timer object is freed before calling sync_vmcs12() routine. A guest user/process could use this flaw to crash the host kernel resulting in a denial of service or, potentially, gain privileged access to a system.

There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue.(CVE-2017-5754) - A non-privileged user is able to mount a fuse filesystem on RHEL 6 or 7 and crash a system if an application punches a hole in a file that does not end aligned to a page boundary.(CVE-2017-15121) - A flaw was found in the Linux kernel when attempting to last seen 2020-06-01 modified 2020-06-02 plugin id 124835 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/124835 title EulerOS Virtualization 3.0.1.0 : kernel (EulerOS-SA-2019-1514) NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2018-1062.NASL description From Red Hat Security Advisory 2018:1062 : An update for kernel is now available for Red Hat Enterprise Linux 7.
