Since {{kernel link|rhel6-testing|042stab076.3}}:
This kernel is still based on 2.6.32-279.22.1.el6 Red Hat kernel, but a set of
security patches has been backported from kernel-2.6.32-358.2.1.el6 RHEL6.4
kernel (RHSA-2013-0630):
* A flaw was found in the way the xen_iret() function in the Linux kernel used the DS (the CPU's Data Segment) register. A local, unprivileged user in a 32-bit, para-virtualized Xen hypervisor guest could use this flaw to crash the guest or, potentially, escalate their privileges. (CVE-2013-0228, Important)
* A flaw was found in the way file permission checks for the "/dev/cpu/[x]/msr" files were performed in restricted root environments (for example, when using a capability-based security model). A local user with the ability to write to these files could use this flaw to escalate their privileges to kernel level, for example, by writing to the SYSENTER_EIP_MSR register. (CVE-2013-0268, Important)
