In the Android kernel in the bootloader there is a possible secure boot bypass.

MEDIUM 6.7EPSS 0.17%

Does this matter?

Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.

Description

In the Android kernel in the bootloader there is a possible secure boot bypass. This could lead to local escalation of privilege with System execution privileges needed. User interaction is needed for exploitation.
