DESCRIPTION
* CVE-2020-12888: Denial-of-service when accessing PCI memory through VFIO.
The VFIO PCI driver can allow users to access disabled PCI memory
regions in certain scenarios, which can lead to a system crash on
some platforms. This flaw could be exploited by a local attacker
to cause a denial-of-service both directly from the host via a
userspace device driver, or from a guest VM that uses VFIO passthrough.
SUPPORT
Ksplice support is available at ksplice-support_ww@oracle.com.
Oracle Linux has released new Ksplice updates for RHCK 8.
