Summary:
The remote host is missing an update for the 'Linux Kernel' Linux Distribution Package(s) announced via the SUSE-SU-2021:2451-1 advisory.

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

Technical Details:
The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: CVE-2021-22555: Fixed an heap out-of-bounds write in net/netfilter/x_tables.c that could allow local provilege escalation. (bsc#1188116) CVE-2021-33909: Fixed an out-of-bounds write in the filesystem layer that allows to obtain full root privileges. (bsc#1188062) CVE-2021-3609: Fixed a race condition in the CAN BCM networking protocol which allows for local privilege escalation. (bsc#1187215) CVE-2021-0605: Fixed an out-of-bounds read which could lead to local information disclosure in the kernel with System execution privileges needed. (bsc#1187601) CVE-2021-0512: Fixed a possible out-of-bounds write which could lead to local escalation of privilege with no additional execution privileges needed. (bsc#1187595) CVE-2021-34693: Fixed a bug in net/can/bcm.c which could allow local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized. (bsc#1187452) CVE-2020-36385: Fixed a use-after-free flaw in ucma.c which allows for local privilege escalation. (bsc#1187050) CVE-2021-0129: Fixed an improper access control in BlueZ that may have allowed an authenticated user to potentially enable information disclosure via adjacent access. (bsc#1186463) CVE-2020-26558: Fixed a flaw in the Bluetooth LE and BR/EDR secure pairing that could permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing. (bsc#1179610) CVE-2020-36386: Fixed an out-of-bounds read in hci_extended_inquiry_result_evt. (bsc#1187038) CVE-2020-24588: Fixed a bug that could allow an adversary to abuse devices that support receiving non-SSP A-MSDU frames to inject arbitrary network packets. (bsc#1185861) CVE-2021-32399: Fixed a race condition in net/bluetooth/hci_request.c for removal of the HCI controller. (bsc#1184611) CVE-2021-33034: Fixed an issue in net/bluetooth/hci_event.c where a use-after-free leads to writing an arbitrary value. (bsc#1186111) CVE-2020-26139: Fixed a bug that allows an Access Point (AP) to forward EAPOL frames to other clients even though the sender has not yet successfully authenticated. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and made it easier to exploit other vulnerabilities in connected clients. (bsc#1186062) CVE-2021-23134: Fixed a use After Free vulnerability in nfc sockets which allows local attackers to elevate their privileges. (bsc#1186060) CVE-2020-24586: Fixed a bug that, under the right circumstances, allows to inject arbitrary network packets and/or exfiltrate user data when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP. (bsc#1185859) CVE-2020-26141: Fixed a flaw that could allows an adversary to inject and possibly ... [Please see the references for more information on the vulnerabilities]

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".
