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).");
