Local information disclosure via missing null check
Published Jun 28, 2023 · Updated Dec 3, 2024
Out-of-bounds read in Android kernel libsitril allows local users to disclose information without additional privileges. BuildSetRadioNode in protocolmiscbuilder.cpp dereferences radio-node data without first checking for a null pointer, causing a read outside the intended memory bounds. Exploitation requires local access but no user interaction or extra execution privileges; the bounded impact is disclosure of data available to the affected component.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
