Description Guilherme de Almeida Suckevicz 2021-06-21 20:07:15 UTC 
In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
