| Description: | 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: Integer overflow in Intel(R) Graphics Drivers (CVE-2020-12362)
kernel: use-after-free caused by a malicious USB device in the drivers/usb/misc/adutux.c driver (CVE-2019-19523)
