kernel-2.6.32-642.11.1.el6

The kernel package contains the Linux kernel (vmlinuz), the core of any
Linux operating system. The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc.

Security issues fixed with this release:

CVE-2016-1583
The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the
Linux kernel before 4.6.3 allows local users to gain privileges or
cause a denial of service (stack memory consumption) via vectors
involving crafted mmap calls for /proc pathnames, leading to recursive
pagefault handling.
CVE-2016-2143
The fork implementation in the Linux kernel before 4.5 on s390
platforms mishandles the case of four page-table levels, which allows
local users to cause a denial of service (system crash) or possibly
have unspecified other impact via a crafted application, related to
arch/s390/include/asm/mmu_context.h and
arch/s390/include/asm/pgalloc.h.

Fixed bugs:

* Use of a multi-threaded workload with high memory mappings sometiems caused a kernel panic, due to a race condition between the context switch and the pagetable upgrade. This update fixes the switch_mm() by using the complete asce parameter instead of the asce_bits parameter. As a result, the kernel no longer panics in the described scenario.
* When iptables created the Transmission Control Protocol (TCP) reset packet, a kernel crash could occur due to uninitialized pointer to the TCP header within the Socket Buffer (SKB). This update fixes the transport header pointer in TCP reset for both IPv4 and IPv6, and the kernel no longer crashes in the described situation.
* Previously, when the Enhanced Error Handling (EEH) mechanism did not block the PCI configuration space access and an error was detected, a kernel panic occurred. This update fixes EEH to fix this problem. As a result, the kernel no longer panics in the described scenario.
* When the lockd service failed to start up completely, the notifier blocks were in some cases registered on a notification chain multiple times, which caused the occurrence of a circular list on the notification chain. Consequently, a soft lock-up or a kernel oops occurred. With this update, the notifier blocks are unregistered if lockd fails to start up completely, and the soft lock-ups or the kernel oopses no longer occur under the described circumstances.
* When the Fibre Channel over Ethernet (FCoE) was configured, the FCoE MaxFrameSize parameter was incorrectly restricted to 1452. With this update, the NETIF_F_ALL_FCOE symbol is no longer ignored, which fixes this bug. MaxFrameSize is now restricted to 2112, which is the correct value.
* When the fnic driver was installed on Cisco UCS Blade Server, the discs were under certain circumstances put into the offline state with the following error message: "Medium access timeout failure. Offlining disk!". This update fixes fnic to set the Small Computer System Interface (SCSI) status as DID_ABORT after a successful abort operation. As a result, the discs are no longer put into the offlined state in the described situation.
