Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to a possible out of bounds read in the DoSetPinControl function of miscservice.cpp due to a missing bounds check. This could lead to local escalation of privilege, requiring System execution privileges. No user interaction is needed for exploitation.

Recommendations For Android kernel, consider applying a patch that includes a bounds check in the DoSetPinControl function to prevent out of bounds reads. As a temporary workaround, restrict access to the miscservice.cpp module to minimize the risk of exploitation.
