Summary
Red Hat Security Advisory: kernel-rt security update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise MRG 2.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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: error in exception handling leads to DoS (CVE-2018-8897)
* kernel: ptrace() incorrect error handling leads to corruption and DoS (CVE-2018-1000199)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Red Hat would like to thank Nick Peterson (Everdox Tech LLC) and Andy Lutomirski for reporting CVE-2018-8897 and Andy Lutomirski for reporting CVE-2018-1000199.
