3. Description:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
* A race condition flaw was found in the way the Linux kernel's KVM
subsystem handled PIT (Programmable Interval Timer) emulation. A guest user
who has access to the PIT I/O ports could use this flaw to crash the host.
(CVE-2014-3611, Important)
* A memory corruption flaw was found in the way the USB ConnectTech
WhiteHEAT serial driver processed completion commands sent via USB Request
Blocks buffers. An attacker with physical access to the system could use
this flaw to crash the system or, potentially, escalate their privileges on
the system. (CVE-2014-3185, Moderate)
* It was found that the Linux kernel's KVM subsystem did not handle the VM
exits gracefully for the invept (Invalidate Translations Derived from EPT)
and invvpid (Invalidate Translations Based on VPID) instructions. On hosts
with an Intel processor and invept/invppid VM exit support, an unprivileged
guest user could use these instructions to crash the guest. (CVE-2014-3645,
CVE-2014-3646, Moderate)
Red Hat would like to thank Lars Bull of Google for reporting
CVE-2014-3611, and the Advanced Threat Research team at Intel Security for
reporting CVE-2014-3645 and CVE-2014-3646.
This update also fixes the following bugs:
* This update fixes several race conditions between PCI error recovery
callbacks and potential calls of the ifup and ifdown commands in the tg3
driver. When triggered, these race conditions could cause a kernel crash.
(BZ#1142570)
* Previously, GFS2 failed to unmount a sub-mounted GFS2 file system if its
parent was also a GFS2 file system. This problem has been fixed by adding
the appropriate d_op->d_hash() routine call for the last component of the
mount point path in the path name lookup mechanism code (namei).
(BZ#1145193)
* Due to previous changes in the virtio-net driver, a Red Hat Enterprise
Linux 6.6 guest was unable to boot with the "mgr_rxbuf=off" option
specified. This was caused by providing the page_to_skb() function with an
incorrect packet length in the driver's Rx path. This problem has been
fixed and the guest in the described scenario can now boot successfully.
(BZ#1148693)
* When using one of the newer IPSec Authentication Header (AH) algorithms
with Openswan, a kernel panic could occur. This happened because the
maximum truncated ICV length was too small. To fix this problem, the
MAX_AH_AUTH_LEN parameter has been set to 64. (BZ#1149083)
* A bug in the IPMI driver caused the kernel to panic when an IPMI
interface was removed using the hotmod script. The IPMI driver has been
fixed to properly clean the relevant data when removing an IPMI interface.
(BZ#1149578)
* Due to a bug in the IPMI driver, the kernel could panic when adding an
IPMI interface that was previously removed using the hotmod script.
This update fixes this bug by ensuring that the relevant shadow structure
is initialized at the right time. (BZ#1149580)
All kernel users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The system must be
rebooted for this update to take effect.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the
Red Hat Network to apply this update are available at
https://access.redhat.com/articles/11258
To install kernel packages manually, use "rpm -ivh [package]". Do not use
"rpm -Uvh" as that will remove the running kernel binaries from your
system. You may use "rpm -e" to remove old kernels after determining that
the new kernel functions properly on your system.
5. Bugs fixed (https://bugzilla.redhat.com/):
1141400 - CVE-2014-3185 Kernel: USB serial: memory corruption flaw
1144825 - CVE-2014-3646 kernel: kvm: vmx: invvpid vm exit not handled
1144835 - CVE-2014-3645 kernel: kvm: vmx: invept vm exit not handled
1144878 - CVE-2014-3611 kernel: kvm: PIT timer race condition
