CVE Names:         CVE-2022-2585 CVE-2022-30594 
====================================================================
1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 9.

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 (v. 9) - aarch64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux AppStream (v. 9) - aarch64, noarch, ppc64le, s390x, x86_64
Red Hat Enterprise Linux BaseOS (v. 9) - 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):

* posix cpu timer use-after-free may lead to local privilege escalation
(CVE-2022-2585)

* Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP
option (CVE-2022-30594)

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):

* kernel crash after reboot of T14/G2 AMD laptop (mt7921e module)
(BZ#2095653)

* execve exit tracepoint not called (BZ#2106661)

* Matrox black screen on VGA output on some systems. (BZ#2112017)

* The kernel needs to offer a way to reseed the Crypto DRBG and atomically
extract random numbers from it (BZ#2121129)

* watchdog BUG: soft lockup - CPU#30 stuck for 34s! [swapper/30:0]
(BZ#2127857)

* Update cifs to 5.16 (BZ#2127858)

* Bad page state in process qemu-kvm  pfn:68a74600 (BZ#2127859)

* vfio zero page mappings fail after 2M instances (BZ#2128791)

* The kernel needs to offer a way to reseed the Crypto DRBG and atomically
extract random numbers from it (part 2) (BZ#2128970)

Enhancement(s):

* Need to enable hpilo to support new HPE RL300 Gen11 for ARM (aarch64)
(BZ#2129453)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

2085300 - CVE-2022-30594 kernel: Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option
2114874 - CVE-2022-2585 kernel: posix cpu timer use-after-free may lead to local privilege escalation
