Description

Security update for the Linux Kernel The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2021-0512: Fixed a possible out of bounds write due to a heap buffer overflow in __hidinput_change_resolution_multipliers. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (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-2020-36386: 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 bsc#1185863) - CVE-2021-29154: Fixed an incorrect computation of branch displacements in the BPF JIT compilers, which could allow to execute arbitrary code within the kernel context. (bsc#1184391) - CVE-2021-32399: Fixed a race condition in net/bluetooth/hci_request.c for removal of the HCI controller. (bsc#1184611) - 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 bsc#1185863) - 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#1185863 bsc#1186062) - 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 bsc#1185863) The following non-security bugs were fixed: - md: do not flush workqueue unconditionally in md_open (bsc#1184081). - md: factor out a mddev_find_locked helper from mddev_find (bsc#1184081). - md: md_open returns -EBUSY when entering racing area (bsc#1184081). - md: split mddev_find (bsc#1184081).
