     The following security bugs were fixed:

  - Unprivileged BPF has been disabled by default to reduce attack surface
       as too many security issues have happened in the past (jsc#SLE-22573)

       You can re-enable via systemctl setting
     /proc/sys/kernel/unprivileged_bpf_disabled to 0.
     (kernel.unprivileged_bpf_disabled = 0)

  - CVE-2021-0941: In bpf_skb_change_head of filter.c, there is a possible
       out of bounds read due to a use after free. This could lead to local
       escalation of privilege with System execution privileges needed. User
       interaction is not needed for exploitation (bnc#1192045).

  - CVE-2021-31916: An out-of-bounds (OOB) memory write flaw was found in
       list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module
       in the Linux kernel A bound check failure allowed an attacker with
       special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds
       memory leading to a system crash or a leak of internal kernel
       information. The highest threat from this vulnerability is to system
       availability (bnc#1192781).

  - CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less
       predictive to avoid information leaks about UDP ports in use.
       (bsc#1191790)

  - CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device
       fails  (bsc#1191961).

  - CVE-2021-43389: There was an array-index-out-of-bounds flaw in the
       detach_capi_ctr function in drivers/isdn/capi/kcapi.c (bnc#1191958).

  - CVE-2021-37159: hso_free_net_device in drivers/net/usb/hso.c called
       unregister_netdev without checking for the NETREG_REGISTERED state,
       leading to a use-after-free and a double free (bnc#1188601).

     The following non-security bugs were fixed:

  - ABI: sysfs-kernel-slab: Document some stats (git-fixes).

  - ALSA: hda: fix general protection fault in azx_runtime_idle (git-fixes).

  - ALSA: hda: Free card instance properly at probe errors (git-fixes).

  - ALSA: hda/realtek: Fix mic mute LED for the HP Spectre x360 14
       (git-fixes).

  - ALSA: hda: Reduce udelay() at SKL+ position reporting (git-fixes).

  - ALSA: hda: Use position buffer for SKL+ again (git-fixes).

  - ALSA: ua101: fix division by zero at probe (git-fixes).

  - ALSA: uapi: Fix a C++ style comment in asound.h (git-fixes).

  - ALSA: usb-audio: Add Audient iD14 to mixer map quirk table (git-fixes).

  - ALSA: usb-audio: Add minimal-mute not ...
