3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es):

An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of instructions (a commonly
used performance optimization). There are three primary variants of the
issue which differ in the way the speculative execution can be exploited.

Note: This issue is present in hardware and cannot be fully fixed via
software update. The updated kernel packages provide software mitigation
for this hardware issue at a cost of potential performance penalty. Please
refer to References section for further information about this issue and
the performance impact.

In this update initial mitigations for IBM Power (PowerPC) and IBM zSeries
(S390) architectures are provided.

* Variant CVE-2017-5715 triggers the speculative execution by utilizing
branch target injection. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
and guest/host boundaries and read privileged memory by conducting targeted
cache side-channel attacks. This fix specifically addresses S390
processors. (CVE-2017-5715, Important)

* Variant CVE-2017-5753 triggers the speculative execution by performing a
bounds-check bypass. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
boundary and read privileged memory by conducting targeted cache
side-channel attacks. This fix specifically addresses S390 and PowerPC
processors. (CVE-2017-5753, Important)

* Variant CVE-2017-5754 relies on the fact that, on impacted
microprocessors, during speculative execution of instruction permission
faults, exception generation triggered by a faulting access is suppressed
until the retirement of the whole instruction block. In a combination with
the fact that memory accesses may populate the cache even when the block is
being dropped and never committed (executed), an unprivileged local
attacker could use this flaw to read privileged (kernel space) memory by
conducting targeted cache side-channel attacks. Note: CVE-2017-5754 affects
Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected
by this issue. This fix specifically addresses PowerPC processors.
(CVE-2017-5754, Important)

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es):

* An integer overflow vulnerability in ip6_find_1stfragopt() function was
found. A local attacker that has privileges (of CAP_NET_RAW) to open raw
socket can cause an infinite loop inside the ip6_find_1stfragopt()
function. (CVE-2017-7542, Moderate)

* The IPv6 fragmentation implementation in the Linux kernel does not
consider that the nexthdr field may be associated with an invalid option,
which allows local users to cause a denial of service (out-of-bounds read
and BUG) or possibly have unspecified other impact via crafted socket and
send system calls. Due to the nature of the flaw, privilege escalation
cannot be fully ruled out, although we believe it is unlikely.
(CVE-2017-9074, Moderate)

* A use-after-free flaw was found in the Netlink functionality of the Linux
kernel networking subsystem. Due to the insufficient cleanup in the
mq_notify function, a local attacker could potentially use this flaw to
escalate their privileges on the system. (CVE-2017-11176, Moderate)

Bug Fix(es):

* Previously, the default timeout and retry settings in the VMBus driver
were insufficient in some cases, for example when a Hyper-V host was under
a significant load. Consequently, in Windows Server 2016, Hyper-V Server
2016, and Windows Azure Platform, when running a Red Hat Enterprise Linux
Guest on the Hyper-V hypervisor, the guest failed to boot or booted with
certain Hyper-V devices missing. This update alters the timeout and retry
settings in VMBus, and Red Hat Enterprise Linux guests now boot as expected
under the described conditions. (BZ#1506145)

* Previously, an incorrect external declaration in the be2iscsi driver
caused a kernel panic when using the systool utility. With this update, the
external declaration in be2iscsi has been fixed, and the kernel no longer
panics when using systool. (BZ#1507512)

* Under high usage of the NFSD file system and memory pressure, if many
tasks in the Linux kernel attempted to obtain the global spinlock to clean
the Duplicate Reply Cache (DRC), these tasks stayed in an active wait in
the nfsd_reply_cache_shrink() function for up to 99% of time. Consequently,
a high load average occurred. This update fixes the bug by separating the
DRC in several parts, each with an independent spinlock. As a result, the
load and CPU utilization is no longer excessive under the described
circumstances. (BZ#1509876)

* When attempting to attach multiple SCSI devices simultaneously, Red Hat
Enterprise Linux 6.9 on IBM z Systems sometimes became unresponsive. This
update fixes the zfcp device driver, and attaching multiple SCSI devices
simultaneously now works as expected in the described scenario.
(BZ#1512425)

* On IBM z Systems, the tiqdio_call_inq_handlers() function in the Linux
kernel incorrectly cleared the device state change indicator (DSCI) for the
af_iucv devices using the HiperSockets transport with multiple input
queues. Consequently, queue stalls on such devices occasionally occurred.
With this update, tiqdio_call_inq_handlers() has been fixed to clear the
DSCI only once, prior to scanning the queues. As a result, queue stalls for
af_iucv devices using the HiperSockets transport no longer occur under the
described circumstances. (BZ#1513314)

* Previously, small data chunks caused the Stream Control Transmission
Protocol (SCTP) to account the receiver_window (rwnd) values incorrectly
when recovering from a "zero-window situation". As a consequence, window
updates were not sent to the peer, and an artificial growth of rwnd could
lead to packet drops. This update properly accounts such small data chunks
and ignores the rwnd pressure values when reopening a window. As a result,
window updates are now sent, and the announced rwnd reflects better the
real state of the receive buffer. (BZ#1514443)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es):

An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of instructions (a commonly
used performance optimization). There are three primary variants of the
issue which differ in the way the speculative execution can be exploited.

Note: This issue is present in hardware and cannot be fully fixed via
software update. The updated kernel packages provide software mitigation
for this hardware issue at a cost of potential performance penalty. Please
refer to References section for further information about this issue and
the performance impact.

In this update initial mitigations for IBM Power (PowerPC) and IBM zSeries
(S390) architectures are provided.

Variant CVE-2017-5753 triggers the speculative execution by performing a
bounds-check bypass. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
boundary and read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2017-5753, Important, PowerPC, S390)

Variant CVE-2017-5715 triggers the speculative execution by utilizing
branch target injection. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor's data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
and guest/host boundaries and read privileged memory by conducting targeted
cache side-channel attacks. (CVE-2017-5715, Important, S390)

Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors,
during speculative execution of instruction permission faults, exception
generation triggered by a faulting access is suppressed until the
retirement of the whole instruction block. In a combination with the fact
that memory accesses may populate the cache even when the block is being
dropped and never committed (executed), an unprivileged local attacker
could use this flaw to read privileged (kernel space) memory by conducting
targeted cache side-channel attacks. (CVE-2017-5754, Important, PowerPC)

Red Hat would like to thank Google Project Zero for reporting these issues.

Bug Fix(es):

* When attempting to reread parent blocks in btree traversal, the xfs code
which deletes extended attributes from an inode assumed that the parent
blocks were still on the cache. Under memory pressure and memory reclaim,
such parent blocks were sometimes removed from the cache. Consequently,
attempts to reread previously cached parent blocks caused the file system
to read invalid memory. This update fixes xfs to reinitialize the pointer
to the parent block buffers after the block has been reread. As a result,
pointers to btree blocks now point to valid memory, and the kernel no
longer crashes due to an invalid memory access. (BZ#1512811)

* The write access check for huge pages did not function correctly on IBM z
Systems. Consequently, if asynchronous I/O reads were used, buffers
sometimes contained zeroes rather than data from a file, even when the
io_getevents() system call reported that the associated read had finished
successfully. This update fixes the write access check in the
gup_huge_pmd() function in memory management, and read data is stored in
asynchronous I/O buffers properly. (BZ#1513315)

* With this update, the rule for iptables reloading has been optimized to
complete faster. (BZ#1514040)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

1519778 - CVE-2017-5753 hw: cpu: speculative execution bounds-check bypass
1519780 - CVE-2017-5715 hw: cpu: speculative execution branch target injection
1519781 - CVE-2017-5754 hw: cpu: speculative execution permission faults handling
