Affected Products:

  * SUSE Linux Enterprise Micro 5.5

  
  
An update that solves 11 vulnerabilities can now be installed.

## Description:

This update for kernel-firmware fixes the following issues:

Update AMD ucode to 20231030 (bsc#1215831):

  * CVE-2022-23820: Failure to validate the AMD SMM communication buffer may
    allow an attacker to corrupt the SMRAM potentially leading to arbitrary code
    execution.
  * CVE-2021-46774: Insufficient input validation in ABL may enable a privileged
    attacker to perform arbitrary DRAM writes, potentially resulting in code
    execution and privilege escalation.
  * CVE-2023-20533: Insufficient DRAM address validation in System Management
    Unit (SMU) may allow an attacker using DMA to read/write from/to invalid
    DRAM address potentially resulting in denial-of-service. 0 CVE-2023-20519: A
    Use-After-Free vulnerability in the management of an SNP guest context page
    may allow a malicious hypervisor to masquerade as the guest's migration
    agent resulting in a potential loss of guest integrity.
  * CVE-2023-20566: Improper address validation in ASP with SNP enabled may
    potentially allow an attacker to compromise guest memory integrity.
  * CVE-2023-20521: TOCTOU in the ASP Bootloader may allow an attacker with
    physical access to tamper with SPI ROM records after memory content
    verification, potentially leading to loss of confidentiality or a denial of
    service.
  * CVE-2021-46766: Improper clearing of sensitive data in the ASP Bootloader
    may expose secret keys to a privileged attacker accessing ASP SRAM,
    potentially leading to a loss of confidentiality.
  * CVE-2022-23830: SMM configuration may not be immutable, as intended, when
    SNP is enabled resulting in a potential limited loss of guest memory
    integrity.
  * CVE-2023-20526: Insufficient input validation in the ASP Bootloader may
    enable a privileged attacker with physical access to expose the contents of
    ASP memory potentially leading to a loss of confidentiality.
  * CVE-2021-26345: Failure to validate the value in APCB may allow an attacker
    with physical access to tamper with the APCB token to force an out-of-bounds
    memory read potentially resulting in a denial of service.
  * CVE-2023-20592: Issue with INVD instruction aka CacheWarpAttack
    (bsc#1215823).
