Name of the Vulnerable Software and Affected Versions Android versions Android-13

Description The issue is related to a possible way to disable user credentials due to resource exhaustion in the list key entries function of utils.rs. This could lead to a local denial of service and requires System execution privileges for exploitation. No user interaction is needed for exploitation.
