# Android timed cache header check allows out-of-bounds write, local privilege escalation

The is_valid_header function in timed_cache_item.c lacks a bounds check, allowing an out-of-bounds write. A local app with System-level execution could use it to escalate privileges.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

In is_valid_header of timed_cache_item.c, there is a possible out-of-bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
