RHSA-2019:1971: Important: kernel-rt security and bug fix update
First published: Tue Jul 30 2019(Updated: )
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.<br>Security Fix(es):<br><li> kernel: insufficient input validation in kernel mode driver in Intel i915 graphics leads to privilege escalation (CVE-2019-11085)</li> <li> kernel: DMA attack using peripheral devices (Thunderclap) (BZ#1690716)</li> <li> kernel: infinite loop in update_blocked_averages() in kernel/sched/fair.c leading to denial of service (CVE-2018-20784)</li> <li> kernel: a NULL pointer dereference in drivers/scsi/megaraid/megaraid_sas_base.c leading to DoS (CVE-2019-11810)</li> <li> kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c, ipmi_si_mem_io.c, ipmi_si_port_io.c (CVE-2019-11811)</li> 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.<br>Bug Fix(es):<br><li> kernel-rt: update to the RHEL8.0.z batch#2 source tree (BZ#1717516)</li>
