[RHSA-2020:3219] kernel-rt security and bug fix update

Severity Moderate
Affected Packages 12
CVEs 2
Info Packages References Vulnerabilities

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

  • kernel: lockdown: bypass through ACPI write via efivar_ssdt (CVE-2019-20908)

  • kernel: lockdown: bypass through ACPI write via acpi_configfs (CVE-2020-15780)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

  • kernel-rt: provide infrastructure to support dual-signing of the kernel (foundation to help address CVE-2020-10713) (BZ#1837441)

  • kernel-rt: update RT source tree to the RHEL-8.2.z3 source tree (BZ#1856816)
