CVE-2022-20304

Account-identity disclosure via Content side channel

Published Aug 11, 2022 · Updated Aug 3, 2024

Observable discrepancy in Content in Google Android 13 allows local users to determine the device user's account through a side channel. Google has not disclosed which Content response or behavior varies with the account state, leaving the specific erroneous operation undisclosed. Local code execution with user privileges is required; no user interaction is needed, and the reported consequence is account-identity disclosure only.
