  script_tag(name:"insight", value:"The openSUSE Leap 15.2 kernel was updated to receive various security and
     bugfixes.

     The following security bugs were fixed:

  - CVE-2021-29650: The netfilter subsystem allowed attackers to cause a
       denial of service (panic) because net/netfilter/x_tables.c and
       include/linux/netfilter/x_tables.h lack a full memory barrier upon the
       assignment of a new table value, aka CID-175e476b8cdf (bnc#1184208).

  - CVE-2021-29155: kernel/bpf/verifier.c performs undesirable out-of-bounds
       speculation on pointer arithmetic, leading to side-channel attacks that
       defeat Spectre mitigations and obtain sensitive information from kernel
       memory. Specifically, for sequences of pointer arithmetic operations,
       the pointer modification performed by the first operation is not
       correctly accounted for when restricting subsequent operations
       (bnc#1184942).

     The following non-security bugs were fixed:

  - ACPI: CPPC: Replace cppc_attr with kobj_attribute (git-fixes).

  - ALSA: core: remove redundant spin_lock pair in snd_card_disconnect
       (git-fixes).

  - ALSA: emu8000: Fix a use after free in snd_emu8000_create_mixer
       (git-fixes).

  - ALSA: hda/cirrus: Add Headphone and Headset MIC Volume Control
       (git-fixes).

  - ALSA: hda/cirrus: Add error handling into CS8409 I2C functions
       (git-fixes).

  - ALSA: hda/cirrus: Add jack detect interrupt support from CS42L42
       companion codec (git-fixes).

  - ALSA: hda/cirrus: Add support for CS8409 HDA bridge and CS42L42
       companion codec (git-fixes).

  - ALSA: hda/cirrus: Cleanup patch_cirrus.c code (git-fixes).

  - ALSA: hda/cirrus: Fix CS42L42 Headset Mic volume control name
       (git-fixes).

  - ALSA: hda/cirrus: Make CS8409 driver more generic by using fixups
       (git-fixes).

  - ALSA: hda/cirrus: Set Initial DMIC volume for Bullseye to -26 dB
       (git-fixes).

  - ALSA: hda/cirrus: Use CS8409 filter to fix abnormal sounds on Bullseye
       (git-fixes).

  - ALSA: hda/realtek - Headset Mic issue on HP platform (git-fixes).

  - ALSA: hda/realtek: Add quirk for Intel Clevo PCx0Dx (git-fixes).

  - ALSA: hda/realtek: GA503 use same quirks as GA401 (git-fixes).

  - ALSA: hda/realtek: Re-order ALC269 ASUS quirk table entries (git-fixes).

  - ALSA: hda/realtek: Re-order ALC269 Acer quirk table entries (git-fixes).

  - ALSA: hda/realtek: Re-order ALC269 Dell quirk table entries (git-fixes).

  - ALSA: hda/realtek: Re-order ALC269 HP quirk table entries (git-fixes).
