                   Red Hat Security Advisory

Synopsis:          Important: kernel security and bug fix update
Advisory ID:       RHSA-2022:5626-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2022:5626
Issue date:        2022-07-19
CVE Names:         CVE-2020-29368 CVE-2021-4197 CVE-2021-4203

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

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 8.4
Extended Update Support.

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 CodeReady Linux Builder EUS (v. 8.4) - aarch64, ppc64le, x86_64
Red Hat Enterprise Linux BaseOS EUS (v.8.4) - aarch64, noarch, ppc64le, s390x, x86_64

3. Description:

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

Security Fix(es):

* kernel: Small table perturb size in the TCP source port generation
algorithm can lead to information leak (CVE-2022-1012)

* kernel: race condition in perf_event_open leads to privilege escalation
(CVE-2022-1729)

* kernel: a use-after-free write in the netfilter subsystem can lead to
privilege escalation to root (CVE-2022-32250)

* kernel: cgroup: Use open-time creds and namespace for migration perm
checks (CVE-2021-4197)

* kernel: Race condition in races in sk_peer_pid and sk_peer_cred accesses
(CVE-2021-4203)

* kernel: the copy-on-write implementation can grant unintended write
access because of a race condition in a THP mapcount check (CVE-2020-29368)

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):

* Failed to reboot after crash trigger (BZ#2060747)

* conntrack entries linger around after test (BZ#2066357)

* Enable nested virtualization (BZ#2079070)

* slub corruption during  LPM of hnv interface (BZ#2081251)

* sleeping function called from invalid context at
kernel/locking/spinlock_rt.c:35 (BZ#2082091)

* Backport request of "genirq: use rcu in kstat_irqs_usr()" (BZ#2083309)

* ethtool -L may cause system to hang (BZ#2083323)

* For isolated CPUs (with nohz_full enabled for isolated CPUs) CPU
utilization statistics are not getting reflected continuously (BZ#2084139)

* Affinity broken due to vector space exhaustion (BZ#2084647)

* kernel memory leak while freeing nested actions (BZ#2086597)

* sync rhel-8.6 with upstream 5.13 through 5.16 fixes and improvements
(BZ#2088037)

* Kernel panic possibly when cleaning namespace on pod deletion
(BZ#2089539)

* Softirq hrtimers are being placed on the per-CPU softirq clocks on
isolcpu’s. (BZ#2090485)

* fix missed wake-ups in rq_qos_throttle try two (BZ#2092076)

* NFS4 client experiencing IO outages while sending duplicate SYNs and
erroneous RSTs during connection reestablishment (BZ#2094334)

* using __this_cpu_read() in preemptible [00000000] code:
kworker/u66:1/937154 (BZ#2095775)

* Need some changes in RHEL8.x kernels. (BZ#2096932)

RedHat: RHSA-2022-5626:01 Important: kernel security and bug fix update

An update for kernel is now available for Red Hat Enterprise Linux 8.4 Extended Update Support

Summary

The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012)
* kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729)
* kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-32250)

* kernel: the copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check (CVE-2020-29368)
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):
* Failed to reboot after crash trigger (BZ#2060747)
