CVE-2021-27363

TITLE

Linux kernel Security hole

Trust: 0.6

sources: CNNVD: CNNVD-202103-523

DESCRIPTION

An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the pointer to an iscsi_transport struct in the kernel module's global variables. Description: Red Hat Advanced Cluster Management for Kubernetes 2.0.10 images Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console—with security policy built in. Bug fix: * RHACM 2.0.10 images (BZ #1940452) 3. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. Bugs fixed (https://bugzilla.redhat.com/): 1940452 - RHACM 2.0.10 images 1944286 - CVE-2021-23358 nodejs-underscore: Arbitrary code execution via the template function 5. 8.2) - aarch64, noarch, ppc64le, s390x, x86_64 3. Bug Fix(es): * System Crash / Core dump while deleting VMs (BZ#1897687) * various patches to stabilize the OPAL error log processing and the powernv dump processing (ESS) (BZ#1907302) * Unable to receive the signal registered using mq_notify(). (BZ#1926111) * SCTP "Address already in use" when no active endpoints from RHEL 8.2 onwards (BZ#1927522) * enable CONFIG_RANDOM_TRUST_CPU (BZ#1928027) * [mm] mm, oom: remove oom_lock from oom_reaper (BZ#1929739) * Configuring the system with non-RT kernel will hang the system (BZ#1930737) * fNIC driver needs a patch fix that addresses crash (BZ#1932460) * OVS mistakenly using local IP as tun_dst for VXLAN packets (?) (BZ#1944670) Enhancement(s): * mlx5: Hairpin Support in Switch Mode (BZ#1924690) * Trace mode enablement in IMC to facilitate perf-kvm support (perf:) (BZ#1929696) * ice: Enable Flow Director Support (BZ#1930780) 4. ========================================================================= Ubuntu Security Notice USN-4901-1 April 06, 2021 linux-lts-trusty vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 ESM Summary: Several security issues were fixed in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-27365) It was discovered that the LIO SCSI target implementation in the Linux kernel performed insufficient identifier checking in certain XCOPY requests. An attacker with access to at least one LUN in a multiple backstore environment could use this to expose sensitive information or modify data. (CVE-2020-28374) Adam Nichols discovered that the iSCSI subsystem in the Linux kernel did not properly restrict access to iSCSI transport handles. A local attacker could use this to cause a denial of service or expose sensitive information (kernel pointer addresses). A local attacker could use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2021-27364) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 ESM: linux-image-3.13.0-185-generic 3.13.0-185.236~12.04.1 linux-image-generic-lts-trusty 3.13.0.185.170 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. Description: The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Bug Fix(es): * kernel-rt possible livelock: WARNING: CPU: 28 PID: 3109 at kernel/ptrace.c:242 ptrace_check_attach+0xdd/0x1a0 (BZ#1925308) * kernel-rt: update RT source tree to the RHEL-8.3.z3 source tree (BZ#1926369) 4. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2021:1071-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:1071 Issue date: 2021-04-06 CVE Names: CVE-2021-27363 CVE-2021-27364 CVE-2021-27365 ==================================================================== 1.
