CVE

CVE-2021-33909

TITLE

Linux kernel Input validation error vulnerability

DESCRIPTION

fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Important: OpenShift Container Platform 4.7.21 security and bug fix update Advisory ID: RHSA-2021:2763-01 Product: Red Hat OpenShift Enterprise Advisory URL: https://access.redhat.com/errata/RHSA-2021:2763 Issue date: 2021-07-26 CVE Names: CVE-2021-33909 CVE-2021-33910 ===================================================================== 1. Summary: An update is now available for Red Hat OpenShift Container Platform 4.7. 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 OpenShift Container Platform 4.7 - noarch, ppc64le, s390x, x86_64 3. Description: Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. The kernel packages contain the Linux kernel, the core of any Linux operating system. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Ansible is a SSH-based configuration management, deployment, and task execution system. The openshift-ansible packages contain Ansible code and playbooks for installing and upgrading OpenShift Container Platform 3. The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. In addition, it supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can also work as a drop-in replacement for sysvinit. Security Fix(es): * kernel: size_t-to-int conversion vulnerability in the filesystem layer (CVE-2021-33909) * systemd: uncontrolled allocation on the stack in function unit_name_path_escape leads to crash (CVE-2021-33910) 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-rt: update RT source tree to the RHEL-8.3.z source tree (BZ#1957359) * Placeholder bug for OCP 4.7.0 rpm release (BZ#1983534) 4. Solution: For OpenShift Container Platform 4.7 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/4.7/release_notes/ocp-4-7-rel ease-notes.html Details on how to access this content are available at https://docs.openshift.com/container-platform/4.7/updating/updating-cluster - -cli.html The system must be rebooted for this update to take effect. 5.

This affects kernel/bpf/core.c and net/core/filter.c. (CVE-2018-25020) Maxim Levitsky discovered that the KVM hypervisor implementation for AMD processors in the Linux kernel did not properly prevent a guest VM from enabling AVIC in nested guest VMs. If you are running a kernel version earlier than the one listed below, please upgrade your kernel as soon as possible. 8.2) - aarch64, ppc64le, x86_64 Red Hat Enterprise Linux BaseOS EUS (v. 8.2) - aarch64, noarch, ppc64le, s390x, x86_64 3. Bug Fix(es): * RHEL8.2 Snapshot2 - tpm: ibmvtpm: Wait for buffer to be set before proceeding (BZ#1933986) * fnic crash from invalid request pointer (BZ#1961707) * [Azure][RHEL8.4] Two Patches Needed To Enable Azure Host Time-syncing in VMs (BZ#1963051) * RHEL kernel 8.2 and higher are affected by data corruption bug in raid1 arrays using bitmaps. (BZ#1969338) 4. ========================================================================= Ubuntu Security Notice USN-5015-1 July 20, 2021 linux-oem-5.10 vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 20.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-oem-5.10: Linux kernel for OEM systems Details: It was discovered that the virtual file system implementation in the Linux kernel contained an unsigned to signed integer conversion error. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-33909) Michael Brown discovered that the Xen netback driver in the Linux kernel did not properly handle malformed packets from a network PV frontend, leading to a use-after-free vulnerability. An attacker in a guest VM could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-28691) It was discovered that the bluetooth subsystem in the Linux kernel did not properly handle HCI device initialization failure, leading to a double-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-3564) It was discovered that the bluetooth subsystem in the Linux kernel did not properly handle HCI device detach events, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-3573) It was discovered that the NFC implementation in the Linux kernel did not properly handle failed connect events leading to a NULL pointer dereference. A local attacker could use this to cause a denial of service. (CVE-2021-3587) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.10.0-1038-oem 5.10.0-1038.40 linux-image-oem-20.04 5.10.0.1038.40 linux-image-oem-20.04b 5.10.0.1038.40 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. (CVE-2021-33909) Or Cohen and Nadav Markus discovered a use-after-free vulnerability in the nfc implementation in the Linux kernel. (CVE-2021-33034) It was discovered that an out-of-bounds (OOB) memory access flaw existed in the f2fs module of the Linux kernel. 8.2) - ppc64le, x86_64 3. Description: This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel. These packages include redhat-release-virtualization-host. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks
