FAQ

Questions about CVE-2026-58946

What does this mean?

A logic error in navigateUpTo in ActivityClientController.java lets a permission check be bypassed. This allows a local escalation of privilege, meaning an app on the device can gain rights it should not have.Source: source.android.com

Am I affected, and how do I check?

The advisory lists Android 16, 16-qpr2 and 17 for this issue. To check a device, look at its Android version and security patch level in the system settings.Source: source.android.com

What should I do about it?

Install the Android security update for your branch that includes the fix (16, 16-qpr2 or 17). No workaround is listed in the facts.Source: source.android.com

Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
