A researcher has successfully used the critical Dirty Pipe vulnerability in Linux to fully root two models of Android phones—a Pixel 6 Pro and Samsung S22—in a hack that demonstrates the power of exploiting the newly discovered OS flaw.

The researcher chose those two handset models for a good reason: They are two of the few—if not the only—devices known to run Android version 5.10.43, the only release of Google's mobile OS that's vulnerable to Dirty Pipe. Because the LPE, or local privilege escalation, vulnerability wasn't introduced until the recently released version 5.8 of the Linux kernel, the universe of exploitable devices—whether mobile, Internet of Things, or servers and desktops—is relatively small.
