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: use-after-free in sound/core/timer.c (CVE-2019-19807)
kernel: out of bounds write in function i2c_smbus_xfer_emulated in drivers/i2c/i2c-core-smbus.c (CVE-2017-18551)
kernel: race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c leads to use-after-free (CVE-2018-20836)
kernel: out of bounds write in i2c driver leads to local escalation of privilege (CVE-2019-9454)
kernel: use after free due to race condition in the video driver leads to local privilege escalation (CVE-2019-9458)
