====================================================================
1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 7.7
Extended Update Support.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux ComputeNode EUS (v. 7.7) - noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.7) - x86_64
Red Hat Enterprise Linux Server EUS (v. 7.7) - noarch, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.7) - ppc64, ppc64le, x86_64

3. Description:

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

Security Fix(es):

* kernel: double free may be caused by the function allocate_trace_buffer
in the file kernel/trace/trace.c (CVE-2017-18595)

* kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c
(CVE-2019-19768)

* Kernel: NetLabel: null pointer dereference while receiving CIPSO packet
with null category may cause kernel panic (CVE-2020-10711)

* kernel: denial of service via ioctl call in network tun handling
(CVE-2018-7191)

* kernel: usb: missing size check in the __usb_get_extra_descriptor()
leading to DoS (CVE-2018-20169)

* kernel: perf_event_open() and execve() race in setuid programs allows a
data leak (CVE-2019-3901)

* kernel: brcmfmac frame validation bypass (CVE-2019-9503)

* kernel: unchecked kstrdup of fwstr in drm_load_edid_firmware leads to
denial of service (CVE-2019-12382)

* kernel: use-after-free in arch/x86/lib/insn-eval.c (CVE-2019-13233)

* kernel: integer overflow and OOB read in drivers/block/floppy.c
(CVE-2019-14283)

* kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c
leads to denial of service (CVE-2019-15916)

* Kernel: net: using kernel space address bits to derive IP ID may
potentially break KASLR (CVE-2019-10639)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

Bug Fix(es):

* Backport: Guest microcode version mismatch on secondary processors
(BZ#1814002)

* Realtek 8111, 8112 stop working after upgrading to 3.10.0-1062
(BZ#1814601)

* [mlx5] Crash on reboot while having VF configured and in switchdev mode
(BZ#1814800)

* qla2xxx: Urgent driver fix needed. Initiator does not relogin to target
after receiving an explicit logout (BZ#1815595)

* High iSCSI read latency resolved by 'tcp: implement coalescing on backlog
queue' (BZ#1817498)

* [RHEL7.8][Azure]Commits to resolve high network latency (BZ#1817934)

* NETDEV WATCHDOG: enp3s0 (r8169): transmit queue 0 timed out (BZ#1822541)

* RHEL7: block mq hang of a blk_mq_freeze_queue_wait(), which waits for a
zero of a q_usage_counter, which never happens (BZ#1824545)

* Kernel crashes with a message fs/fscache/operation.c:449! (BZ#1826293)

* kernel BUG at fs/fscache/operation.c:70! FS-Cache: 4 == 5 is false -
current state is FSCACHE_OP_ST_COMPLETE but should be FSCACHE_OP_CANCELLED
in fscache_enqueue_operation (BZ#1839756)

4. Solution:

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