Red Hat Bugzilla – Bug 1464473
CVE-2017-7518 Kernel: KVM: debug exception via syscall emulation
Last modified: 2017-07-10 02:46:50 EDT
Linux kernel built with the Kernel-based Virtual Machine(CONFIG_KVM) support
is vulnerable to an incorrect debug exception(#DB) error. It could occur while
emulating a syscall instruction.
A user/process inside guest could use this flaw to potentially escalate their
privileges inside guest.
Note: Linux guests are not affected.
Created kernel tracking bugs for this issue:
Affects: fedora-all [bug 1464474]
This issue does not affect the versions of the kernel package as shipped with
Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2.
This issue affects the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 7. Future kernel updates for Red Hat Enterprise Linux 7
may address this issue.
