Actively exploited vulnerability
Google Pixel: improper access control flaw under attack
CVE-2026-58704 · Google Pixel Improper Authorization Vulnerability
What is affected
Google Pixel is found on ordinary personal computers and phones, so this is not only a problem for companies. If you use it and have not updated since the fix was released, you are exposed.
Google Pixel devices contain an improper authorization vulnerability in the cellular modem. A logic error may allow an attacker to bypass permission checks and escalate privileges.
What an attacker can do
This is a improper access control flaw. It lets an attacker perform actions or reach data that should be restricted to authorised users.
- How it is reached
- From the same local network
- Access the attacker needs
- No account needed
- Does the victim have to do something?
- No, works without the victim doing anything
What to do
- Update Google Pixel now. Open the update or "About" screen, install whatever is offered and restart the app or device, because the fix is not active until you do.
- Turn on automatic updates so the next fix arrives without you having to look for it.
- If your device is too old to receive this update, stop using the affected app for anything sensitive and plan a replacement.
Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

How urgent is it
CISA added this vulnerability to its Known Exploited Vulnerabilities catalogue on September 16, 2026, which means there is reliable evidence of attacks in the wild. US federal agencies must fix it by September 19, 2026, a deadline that has already passed. That deadline does not bind anyone else, but it shows how seriously the agency rates it.
The EPSS model estimates a 0.6% probability that this flaw will be exploited somewhere in the next 30 days. That is higher than 47% of all scored vulnerabilities.
Its CVSS severity score is 8.8 out of 10 (high), as recorded in the US National Vulnerability Database.
Technical description
In Cellular Modem, there is a possible permission bypass due to a logic error in the code. This could lead to remote (proximal/adjacent) escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
