Published: 2021-08-15 03:02:11
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

The remote host is missing an update for the 'the' Linux Distribution Package(s) announced via the openSUSE-SU-2021:2687-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2021-3659: Fixed a NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c (bsc#1188876). - CVE-2021-21781: Fixed a information disclosure vulnerability in the ARM SIGPAGE (bsc#1188445). - CVE-2021-22543: Fixed improper handling of VM_IOVM_PFNMAP vmas in KVM, which could bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allowed users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation (bsc#1186482). - CVE-2021-37576: Fixed an issue on the powerpc platform, where a KVM guest OS user could cause host OS memory corruption via rtas_args.nargs (bsc#1188838). - CVE-2021-3609: Fixed a potential local privilege escalation in the CAN BCM networking protocol (bsc#1187215). - CVE-2021-3612: Fixed an out-of-bounds memory write flaw in the joystick devices subsystem. This flaw allowed a local user to crash the system or possibly escalate their privileges on the system. (bsc#1187585) - CVE-2021-35039: Fixed mishandling of signature verification. Without CONFIG_MODULE_SIG, verification that a kernel module is signed, for loading via init_module, did not occur for a module.sig_enforce=1 command-line argument (bsc#1188080). The following non-security bugs were fixed: - ACPI: AMBA: Fix resource name in /proc/iomem (git-fixes). - ACPI: APEI: fix synchronous external aborts in user-mode (git-fixes). - ACPI: DPTF: Fix reading of attributes (git-fixes). - ACPI: EC: Make more Asus laptops use ECDT _GPE (git-fixes). - ACPI: PM / fan: Put fan device IDs into separate header file (git-fixes). - ACPI: bus: Call kobject_put() in acpi_init() error path (git-fixes). - ACPI: processor idle: Fix up C-state latency if not ordered (git-fixes). - ACPI: property: Constify stubs for CONFIG_ACPI=n case (git-fixes). - ACPI: resources: Add checks for ACPI IRQ override (git-fixes). - ACPI: sysfs: Fix a buffer overrun problem with description_show() (git-fixes). - ACPI: video: Add quirk for the Dell Vostro 3350 (git-fixes). - ACPICA: Fix memory leak caused by _CID repair function (git-fixes). - ALSA: ac97: fix PM reference leak in ac97_bus_remove() (git-fixes). - ALSA: bebob: add support for ToneWeal FW66 (git-fixes).

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
