The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: bad kfree in auditfilter.c may lead to escalation of privilege (CVE-2020-0444)

  • kernel: locking issue in drivers/tty/tty_jobctrl.c can lead to an use-after-free (CVE-2020-29661)

  • kernel: performance counters race condition use-after-free (CVE-2020-14351)

  • kernel: ICMP rate limiting can be used for DNS poisoning attack (CVE-2020-25705)

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):

  • [Hyper-V][RHEL-8] Request to included a commit that adds a timeout to vmbus_wait_for_unload (BZ#1913530)

  • [CKI kernel builds]: x86 binaries in non-x86 kernel rpms breaks systemtap (BZ#1929908)

  • rpmbuild cannot build the userspace RPMs in the kernel package when the kernel itself is not built (BZ#1929912)
