     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 privilege escalation.
       (bsc#1188116)

  - CVE-2021-33624: Fixed a bug which allows unprivileged BPF program to
       leak the contents of arbitrary kernel memory (and therefore, of all
       physical memory) via a side-channel. (bsc#1187554)

  - 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-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. (bnc#1179610)

  - 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-2021-0129: Fixed an improper access control in BlueZ that may have
       allowed an authenticated user to potentially enable information
       disclosure via adjacent access. (bnc#1186463)

  - 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-2021-33909: Fixed an out-of-bounds write in the filesystem layer
       that allows to andobtain 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-2020-36385: Fixed a use-after-free flaw in ucma.c which allows for
       local privilege escalation. (bsc#1187050)

  - CVE-2021-33200: Fix leakage of uninitialized bpf stack under
       speculation. (bsc#1186484)

     The following non-security bugs were fixed:

  - af_packet: fix the tx skb protocol in raw sockets with ETH_P_ALL
       (bsc#1176081).

  - kabi: preserve struct header_ops after bsc#1176081 fix (bsc#1176081).

  - net: Do not set transport offset to invalid value (bsc#1176081) ...
