3. Description:

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

Security Fix(es):

* kernel: Use-after-free in __blk_drain_queue() function in
block/blk-core.c (CVE-2018-20856)

* kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi
driver (CVE-2019-14816)

* kernel: heap-based buffer overflow in mwifiex_process_country_ie()
function in drivers/net/wireless/marvell/mwifiex/sta_ioctl.c
(CVE-2019-14895)

* kernel: buffer overflow in cfg80211_mgd_wext_giwessid in
net/wireless/wext-sme.c (CVE-2019-17133)

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):

* [PATCH] perf: Fix a race between ring_buffer_detach() and
