=====================================================================

1. Summary:

An update for kernel-alt is now available for Red Hat Enterprise Linux 7.

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 for ARM and IBM Power LE (POWER9) Server (v. 7) - aarch64, noarch, ppc64le, s390x
Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server Optional (v. 7) - aarch64, noarch, ppc64le

3. Description:

The kernel-alt packages provide the Linux kernel version 4.x.

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: out of bounds write in function i2c_smbus_xfer_emulated in
drivers/i2c/i2c-core-smbus.c (CVE-2017-18551)

* kernel: out of bounds write in i2c driver leads to local escalation of
privilege (CVE-2019-9454)

* kernel: denial of service in in xfs_setattr_nonsize in fs/xfs/xfs_iops.c
(CVE-2019-15538)

* kernel: mounting a crafted ext4 filesystem image, performing some
operations, and unmounting can lead to a use-after-free in ext4_put_super
in fs/ext4/super.c (CVE-2019-19447)

* kernel: a malicious USB device in the drivers/input/ff-memless.c leads to
use-after-free (CVE-2019-19524)

* kernel: out-of-bounds read in set_fdc in drivers/block/floppy.c
(CVE-2020-9383)

* kernel: null pointer dereference in dlpar_parse_cc_property in
arch/powerrc/platforms/pseries/dlpar.c causing denial of service
(CVE-2019-12614)

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.
