- CVE-2020-0543 Special Register Buffer Data Sampling (SRBDS),
INTEL-SA-00320
- CVE-2020-0548 Vector Register Sampling, INTEL-SA-00329
- CVE-2020-0549 L1D Eviction Sampling, INTEL-SA-00329
- Microcode fixes include update for 0x00050654 to address lockups
on certain Skylake processors (LP: #1854764)
* Remaining changes:
- Ship tmpfiles.d snippet to attempt late loading of microcode
during boot, in case early loading of microcode did not
happen. Early microcode loading might not happen if booting
without initramfs or a missbuilt one.
- debian/initramfs.hook: Do not override preset defaults from
auto-exported conf snippets loaded by initramfs-tools.
