RedHat: RHSA-2020-2104:01 Important: kernel-alt security and bug fix update
Summary
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)

score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
Bug Fix(es):
* [7.5-alt][ext4/xfstests generic/468] fix fdatasync(2) after fallocate(2)
operation (upstream fixed) [rhel-alt-7.6.z] (BZ#1554273)
* [RHEL-ALT-7.6.z][arm64] CN99xx: DIMM errors not populated in EDAC sysfs
(BZ#1778697)
