Description msiddiqu 2020-03-31 18:59:30 UTC 
A vulnerability was found in vl53L0 driver in Kernel where there is a possible out of bounds write due to a permissions bypass. This could lead to local escalation of privilege due to a set_fs() call without restoring the previous limit with System execution privileges needed. User interaction is not needed for exploitation.
