    - CVE-2024-36350 (AMD-SB-7029)
      A transient execution vulnerability in some AMD processors may allow
      an attacker to infer data from previous stores, potentially resulting
      in the leakage of privileged information.
    - CVE-2024-36357 (AMD-SB-7029)
      A transient execution vulnerability in some AMD processors may allow
      an attacker to infer data in the L1D cache, potentially resulting in
      the leakage of sensitive information across privileged boundaries.
  * Remaining changes:
    - initramfs-tools hook (debian/initramfs.hook):
      + Default to 'early' instead of 'auto' when building with
        MODULES=most
      + Do not override preset defaults from auto-exported conf
        snippets loaded by initramfs-tools.
  * Also Update AMD PMF TA Firmware to v3.1 to match the upstream git tag. (LP: #2121119)
