SUSE: Security Advisory (SUSE-SU-2021:2451-1)

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

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]
