Summary
Red Hat Security Advisory: kernel-rt security and bug fix update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 8.2 Extended Update Support.
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: bad kfree in auditfilter.c may lead to escalation of privilege (CVE-2020-0444)
* kernel: Local buffer overflow in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c (CVE-2020-25211)
* 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):
* kernel-rt: update RT source tree to the latest RHEL-8.2.z7 Batch source tree (BZ#1915947)
* kernel-rt possible livelock: WARNING: CPU: 28 PID: 3109 at kernel/ptrace.c:242 ptrace_check_attach+0xdd/0x1a0 (BZ#1925309)
