3. Description:

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

Security Fix(es):

* kernel: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in
the Linux kernel lacks a certain upper-bound check, leading to a buffer
overflow (CVE-2019-17666)

* Kernel: KVM: export MSR_IA32_TSX_CTRL to guest - incomplete fix for TAA
(CVE-2019-11135) (CVE-2019-19338)

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):

* Slow console output with ast (Aspeed) graphics driver (BZ#1780146)

* VFS: Busy inodes after unmount of loop0 when encountering duplicate
directory inodes (BZ#1781158)

* RHEL 7.7 long I/O stalls with bnx2fc from not masking off scope bits of
retry delay value (BZ#1795648)

* System Crash on vport creation (NPIV on FCoE) (BZ#1796363)

* A directory on a gfs2 filesystem appears corrupt on nodeB after nodeA
renames the directory (BZ#1796430)

* [GSS] Can't access the mount point due to possible blocking of i/o on rbd
(BZ#1796434)

* [xfstests]: copy_file_range cause corruption on rhel-7 (BZ#1797966)

* port show-kabi to python3 (BZ#1806928)

* top shows super high loads when tuned profile realtime-virtual-host is
applied (BZ#1808028)

Enhancement(s):

* scsi: qla2xxx: Fix panic in qla_dfs_tgt_counters_show' (BZ#1791594)

* [Cavium 7.7 Feat] qla2xxx: Update to latest upstream. (BZ#1797503)
