CVE-2010-5313

Status Candidate

Overview

Race condition in arch/x86/kvm/x86.c in the Linux kernel before 2.6.38 allows L2 guest OS users to cause a denial of service (L1 guest OS crash) via a crafted instruction that triggers an L2 emulation failure report, a similar issue to CVE-2014-7842.

Red Hat Security Advisory 2016-0855-01

Red Hat Security Advisory 2016-0855-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: It was found that reporting emulation failures to user space could lead to either a local or a L2->L1 denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain systems, HPET is mapped to userspace as part of vdso and thus an unprivileged user may generate MMIO transactions this way.

Red Hat Security Advisory 2015-2152-02

Red Hat Security Advisory 2015-2152-02 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's file system implementation handled rename operations in which the source was inside and the destination was outside of a bind mount. A privileged user inside a container could use this flaw to escape the bind mount and, potentially, escalate their privileges on the system. A race condition flaw was found in the way the Linux kernel's IPC subsystem initialized certain fields in an IPC object structure that were later used for permission checking before inserting the object into a globally visible list. A local, unprivileged user could potentially use this flaw to elevate their privileges on the system.
