(bsc#1188116)\n- CVE-2021-33909: Fixed an out-of-bounds write in the filesystem layer that allows to obtain full root privileges. (bsc#1188062)\n- CVE-2021-3609: Fixed a race condition in the CAN BCM networking protocol which allows for local privilege escalation. (bsc#1187215)\n- 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)\n- 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)\n- 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)\n- CVE-2020-36385: Fixed a use-after-free flaw in ucma.c which allows for local privilege escalation. (bsc#1187050)\n- 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)\n- 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)\n- CVE-2020-36386: Fixed an out-of-bounds read in hci_extended_inquiry_result_evt. (bsc#1187038)\n- 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)\n- CVE-2021-32399: Fixed a race condition in net/bluetooth/hci_request.c for removal of the HCI controller. (bsc#1184611)\n- 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)\n- 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)\n- CVE-2021-23134: Fixed a use After Free vulnerability in nfc sockets which allows local attackers to elevate their privileges. (bsc#1186060)\n- 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)\n- CVE-2020-26141: Fixed a flaw that could allows an adversary to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-confidentiality protocol. (bsc#1185987)\n- CVE-2020-26145: Fixed a bug in the WEP, WPA, WPA2, and WPA3 implementations that could allows an adversary to inject arbitrary network packets. (bsc#1185860)\n- CVE-2020-24587: Fixed a bug that allows an adversary to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (bsc#1185862)\n- CVE-2020-26147: Fixed a bug in the WEP, WPA, WPA2, and WPA3 implementations that could allows an adversary to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames. (bsc#1185987)\n\nThe following non-security bugs were fixed:\n\n- kABI: Fix kABI after modifying struct __call_single_data (bsc#1180846).\n- kernel/smp: add boot parameter for controlling CSD lock debugging (bsc#1180846).\n- kernel/smp: Add source and destination CPUs to __call_single_data (bsc#1180846).\n- kernel/smp: make csdlock timeout depend on boot parameter (bsc#1180846).\n- kernel/smp: Provide CSD lock timeout diagnostics (bsc#1180846).\n- Update config files: activate CONFIG_CSD_LOCK_WAIT_DEBUG for x86 (bsc#1180846).\n- Update config files: disable CONFIG_CSD_LOCK_WAIT_DEBUG (bsc#1180846).\n","id":"SUSE-SU-2021:2406-1","modified":"2021-07-20T12:40:03Z","published":"2021-07-20T12:40:03Z","references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2021/suse-su-20212406-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1179610"},{"type":"REPORT","url":"https://bugzilla.suse.com/1180846"},{"type":"REPORT","url":"https://bugzilla.suse.com/1184611"},{"type":"REPORT","url":"https://bugzilla.suse.com/1185859"},{"type":"REPORT","url":"https://bugzilla.suse.com/1185860"},{"type":"REPORT","url":"https://bugzilla.suse.com/1185861"},{"type":"REPORT","url":"https://bugzilla.suse.com/1185862"},{"type":"REPORT","url":"https://bugzilla.suse.com/1185863"},{"type":"REPORT","url":"https://bugzilla.suse.com/1185898"},{"type":"REPORT","url":"https://bugzilla.suse.com/1185987"},{"type":"REPORT","url":"https://bugzilla.suse.com/1186060"},{"type":"REPORT","url":"https://bugzilla.suse.com/1186062"},{"type":"REPORT","url":"https://bugzilla.suse.com/1186111"},{"type":"REPORT","url":"https://bugzilla.suse.com/1186390"},{"type":"REPORT","url":"https://bugzilla.suse.com/1186463"},{"type":"REPORT","url":"https://bugzilla.suse.com/1187038"},{"type":"REPORT","url":"https://bugzilla.suse.com/1187050"},{"type":"REPORT","url":"https://bugzilla.suse.com/1187215"},{"type":"REPORT","url":"https://bugzilla.suse.com/1187452"},{"type":"REPORT","url":"https://bugzilla.suse.com/1187595"},{"type":"REPORT","url":"https://bugzilla.suse.com/1187601"},{"type":"REPORT","url":"https://bugzilla.suse.com/1187934"},{"type":"REPORT","url":"https://bugzilla.suse.com/1188062"},{"type":"REPORT","url":"https://bugzilla.suse.com/1188116"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-24586"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-24587"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-24588"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-26139"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-26141"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-26145"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-26147"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-26558"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-36385"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2020-36386"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-0129"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-0512"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-0605"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-22555"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-23134"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-32399"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-33034"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-33909"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-34693"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2021-3609"}],"related":["CVE-2020-24586","CVE-2020-24587","CVE-2020-24588","CVE-2020-26139","CVE-2020-26141","CVE-2020-26145","CVE-2020-26147","CVE-2020-26558","CVE-2020-36385","CVE-2020-36386","CVE-2021-0129","CVE-2021-0512","CVE-2021-0605","CVE-2021-22555","CVE-2021-23134","CVE-2021-32399","CVE-2021-33034","CVE-2021-33909","CVE-2021-34693","CVE-2021-3609"],"summary":"Security update for the Linux Kernel","upstream":["CVE-2020-24586","CVE-2020-24587","CVE-2020-24588","CVE-2020-26139","CVE-2020-26141","CVE-2020-26145","CVE-2020-26147","CVE-2020-26558","CVE-2020-36385","CVE-2020-36386","CVE-2021-0129","CVE-2021-0512","CVE-2021-0605","CVE-2021-22555","CVE-2021-23134","CVE-2021-32399","CVE-2021-33034","CVE-2021-33909","CVE-2021-34693","CVE-2021-3609"]}
