Local information disclosure via unchecked cell list bounds
Published Jan 3, 2025 · Updated Jan 3, 2025
Out-of-bounds read in Google Cloud Android's Exynos RIL allows local users to disclose information from affected Pixel devices. GetCellInfoList() in protocolnetadapter.cpp reads beyond a buffer because it omits a bounds check before accessing cell information. Exploitation requires prior compromise of the baseband firmware, needs no user interaction, and exposes data without reported modification or interruption.

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.
