[slackware-security]  kernel-firmware (SSA:2023-205-01)

New kernel-firmware packages are available for Slackware 14.2, 15.0,
and -current to fix a security issue.


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/kernel-firmware-20230724_59fbffa-noarch-1.txz:  Upgraded.
  AMD microcode updated to fix a use-after-free in AMD Zen2 processors.
  From Tavis Ormandy's annoucement of the issue:
    "The practical result here is that you can spy on the registers of other
    processes. No system calls or privileges are required.
    It works across virtual machines and affects all operating systems.
    I have written a poc for this issue that's fast enough to reconstruct
    keys and passwords as users log in."
