CVE-2023-30648

Local denial of service via unchecked concatenation

Published Jul 6, 2023 · Updated Oct 24, 2024

Stack out-of-bounds write in RILD on Samsung Mobile Devices before SMR Jul-2023 Release 1 allows attackers to crash Android. IpcRxImeiUpdateImeiNoti reads an unchecked count from a baseband IPC message and repeatedly appends converted failure descriptions with sprintf into a fixed 240-byte stack buffer. A compromised baseband runtime must send the crafted IPC message; the documented consequence is an Android radio-context service crash, not code execution.
