3. Description:

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

Security Fix(es):

* kernel: perf_event_parse_addr_filter memory (CVE-2020-25704)

* kernel: fuse: fuse_do_getattr() calls make_bad_inode() in inappropriate
situations (CVE-2020-36322)

* kernel: Heap buffer overflow in firedtv driver (CVE-2021-42739)

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):

* A gfs2 withdrawal occurs function = gfs2_setbit, file = fs/gfs2/rgrp.c,
line = 109 (BZ#1364234)

* i40e SR-IOV TX driver issue detected on VF 7 - VF connectivity loose
after VF down/up (BZ#1977246)

* duplicate ACK not sent when expected (BZ#1990665)

* [kernel-debug] BUG: bad unlock balance detected! when running LTP
read_all (BZ#2006536)

* Rudimentary support for AMD Milan - Call init_amd_zn() om Family 19h
processors (BZ#2019218)

* A VM with <=8 CPUs handles all the Mellanox NIC interrupts on CPU0 only,
causing low performance (BZ#2019272)

* fix _PSD override quirk for AMD family 19h+ (BZ#2019588)

* generic_file_aio_read returns 0 when interrupted early with a fatal
signal (BZ#2020857)
