Security Fix(es):
* Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM)
support is vulnerable to a null pointer dereference flaw. It could occur on
x86 platform, when emulating an undefined instruction. An attacker could
use this flaw to crash the host kernel resulting in DoS. (CVE-2016-8630,
Important)
* A race condition issue leading to a use-after-free flaw was found in the
way the raw packet sockets implementation in the Linux kernel networking
subsystem handled synchronization while creating the TPACKET_V3 ring
buffer. A local user able to open a raw packet socket (requires the
CAP_NET_RAW capability) could use this flaw to elevate their privileges on
the system. (CVE-2016-8655, Important)
* A flaw was discovered in the Linux kernel's implementation of VFIO. An
attacker issuing an ioctl can create a situation where memory is corrupted
and modify memory outside of the expected area. This may overwrite kernel
memory and subvert kernel execution. (CVE-2016-9083, Important)
* The use of a kzalloc with an integer multiplication allowed an integer
overflow condition to be reached in vfio_pci_intrs.c. This combined with
CVE-2016-9083 may allow an attacker to craft an attack and use unallocated
memory, potentially crashing the machine. (CVE-2016-9084, Moderate)
Red Hat would like to thank Philip Pettersson for reporting CVE-2016-8655.
