The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists in kernel/time/alarmtimer.c within the alarm_timer_nsleep function. A local user can trigger integer overflow due to ktime_add_safe is not used and escalate privileges on the system.
3) Cross-site scripting (CVE-ID: CVE-2018-13055)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
