CVE-2021-33909

TITLE

Kernel Live Patch Security Notice LSN-0079-1

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. If you are running a kernel version earlier than the one listed below, please upgrade your kernel as soon as possible. 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-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. 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. 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. 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. 7.7) - ppc64, ppc64le, x86_64 3. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2021:2725-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:2725 Issue date: 2021-07-20 CVE Names: CVE-2019-20934 CVE-2020-11668 CVE-2021-33033 CVE-2021-33034 CVE-2021-33909 ==================================================================== 1.
