This kernel update is based on upstream 5.10.12 and fixes atleast the

have a kernel stack use-after-free during fault handling, allowing local
users to execute code in the kernel (CVE-2021-3347).
It also adds the following fixes:
- ALSA: hda: Add Cometlake-R PCI ID
- ALSA: hda: Add AlderLake-P PCI ID and HDMI codec vid
- ALSA: hda/via: Apply the workaround generically for Clevo machines
- ASoC: AMD Renoir - refine DMI entries for some Lenovo products
- crypto: arm64/sha - add missing module aliases
- drm/amdgpu: Add Missing Sienna Cichlid DID
- drm/gpu/nouveau/dispnv50: Restore pushing of all data
