Title:	RedHat Update for kernel RHSA-2016:1033-01
Summary:	The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory. Vulnerability Insight: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * A flaw was found in the way the Linux kernel's ASN.1 DER decoder processed certain certificate files with tags of indefinite length. A local, unprivileged user could use a specially crafted X.509 certificate DER file to crash the system or, potentially, escalate their privileges on the system. (CVE-2016-0758, Important) Red Hat would like to thank Philip Pettersson of Samsung for reporting this issue. Bug Fix(es): * Under certain conditions, the migration threads could race with the CPU hotplug, which could cause a deadlock. A set of patches has been provided to fix this bug, and the deadlock no longer occurs in the system. (BZ#1299338) * A bug in the code that cleans up revoked delegations could previously cause a soft lockup in the NFS server. This patch fixes the underlying source code, so the lockup no longer occurs. (BZ#1311582) * The second attempt to reload Common Application Programming Interface (CAPI) devices on the little-endian variant of IBM Power Systems previously failed. The provided set of patches fixes this bug, and reloading works as intended. (BZ#1312396) * Due to inconsistencies in page size of IOMMU, the NVMe device, and the kernel, the BUG_ON signal previously occurred in the nvme_setup_prps() function, leading to the system crash while setting up the DMA transfer. The provided patch sets the default NVMe page size to 4k, thus preventing the system crash. (BZ#1312399) * Previously, on a system using the Infiniband mlx5 driver used for the SRP stack, a hard lockup previously occurred after the kernel exceeded time with lock held with interrupts blocked. As a consequence, the system panicked. This update fixes this bug, and the system no longer panics in this situation. (BZ#1313814) * On the little-endian variant of IBM Power Systems, the kernel previously crashed in the bitmap_weight() function while running the memory affinity script. The provided patch fortifies the topology setup and prevents sd- child from being set to NULL when it is already NULL. As a result, the memory affinity script runs successfully. (BZ#1316158) * When a KVM guest wrote random values to the special-purpose registers (SPR) Instruction Authority Mask Register (IAMR), the guest and the corresponding QEMU process previously hung. This update adds the code which sets SPRs to a suitable neutral value on guest exit, thus fixing this bug. (BZ#1316636) * Under heavy iSCSI traffic load, the system previously panicked due to a race in the locking code leading to a ...
