CVE-2023-44128

System-privileged file deletion via post-delete signature check

Published Sep 27, 2023 · Updated Sep 20, 2024

Time-of-check time-of-use race in LGInstallService on LG Electronics LG V60 ThinQ 5G Android 4 through 13 allows attackers to delete arbitrary files. The exported com.lge.lginstallservies.InstallService AIDL service deletes the supplied file before installPackageVerify() performs signature validation, so attacker-controlled conditions can prevent the check. Local access and user interaction are required; the result is attacker-selected file deletion with system privilege rather than arbitrary code execution.
