CVE

CVE-2021-45485

TITLE

Linux kernel Encryption problem vulnerability

DESCRIPTION

In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. Bug Fix(es): * update RT source tree to the RHEL-8.4.z12 source tree (BZ#2119160) * using __this_cpu_add() in preemptible [00000000] - caller is __mod_memcg_lruvec_state+0x69/0x1c0 [None8.4.0.z] (BZ#2124454) 4. The following packages have been upgraded to a later upstream version: kernel (4.18.0). Security Fix(es): * A use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588) * Information leak in the IPv6 implementation (CVE-2021-45485) * Information leak in the IPv4 implementation (CVE-2021-45486) * Incomplete cleanup of multi-core shared buffers (aka SBDR) (CVE-2022-21123) * Incomplete cleanup of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125) * Incomplete cleanup in specific special register write operations (aka DRPW) (CVE-2022-21166) 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): * DR, Ignore modify TTL if ConnectX-5 doesn't support it (BZ#2075549) * execve exit tracepoint not called (BZ#2106663) * Unable to boot RHEL-8.6 on Brazos max. config (Install is success) (BZ#2107475) * "vmcore failed, _exitcode:139" error observed while capturing vmcore during fadump after memory remove. incomplete vmcore is captured. (BZ#2107490) * soft lockups under heavy I/O load to ahci connected SSDs (BZ#2110773) * Allow substituting custom vmlinux.h for the build (BZ#2116407) 4.

Description: The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Description: Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the container images for Red Hat OpenShift Container Platform 4.8.53. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHBA-2022:7873 Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes: https://docs.openshift.com/container-platform/4.8/release_notes/ocp-4-8-release-notes.html Security Fix(es): * go-getter: command injection vulnerability (CVE-2022-26945) * go-getter: unsafe download (issue 1 of 3) (CVE-2022-30321) * go-getter: unsafe download (issue 2 of 3) (CVE-2022-30322) * go-getter: unsafe download (issue 3 of 3) (CVE-2022-30323) 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. Solution: For OpenShift Container Platform 4.8 see the following documentation, which will be updated shortly for this release, for important instructions on how to upgrade your cluster and fully apply this asynchronous errata update: https://docs.openshift.com/container-platform/4.8/release_notes/ocp-4-8-release-notes.html You may download the oc tool and use it to inspect release image metadata for x86_64, s390x, and ppc64le architectures. The image digests may be found at https://quay.io/repository/openshift-release-dev/ocp-release?tab=tags The sha values for the release are: (For x86_64 architecture) The image digest is sha256:ac2bbfa7036c64bbdb44f9a74df3dbafcff1b851d812bf2a48c4fabcac3c7a53 (For s390x architecture) The image digest is sha256:ac2c74a664257cea299126d4f789cdf9a5a4efc4a4e8c2361b943374d4eb21e4 (For ppc64le architecture) The image digest is sha256:53adc42ed30ad39d7117837dbf5a6db6943a8f0b3b61bc0d046b83394f5c28b2 All OpenShift Container Platform 4.8 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift Console or the CLI oc command.
