Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 28 November 2024). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

In shouldHideDocument of ExternalStorageProvider.java, there is a possible bypass of a file path filter designed to prevent access to sensitive directories due to incorrect unicode normalization. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
