Local information disclosure via bounds-check error
Published Dec 8, 2023 · Updated Aug 2, 2024
Information disclosure in Google Android kernel allows local users to read data via an out-of-bounds read in GetSizeOfEenlRecords. The protocoladapter.cpp function performs an incorrect bounds check before sizing EENL records, permitting reads beyond the intended buffer. Exploitation requires local access but no additional execution privileges or user interaction, and the disclosed data impact is confidentiality only.
