Information disclosure via jpg driver use-after-free

Published Oct 8, 2023 · Updated Sep 19, 2024

Use-after-free in the UNISOC jpg driver on Android 13 allows local users with high privileges to disclose information. UNISOC attributes the stale object lifetime to a logic error but has not disclosed the responsible function, object, or input path. Its prose calls the impact remote and privilege-free, but its published CVSS assessment requires local access and high privileges.
