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)
