CVE-2023-21224Network attack vector

Remote information disclosure via heap over-read

Published Jun 28, 2023 · Updated Dec 3, 2024

Out-of-bounds read in the Google Pixel Android kernel allows remote attackers to disclose memory via crafted modem result data. ss_ProcessReturnResultComponent in ss_MmConManagement.c reads beyond a heap buffer while processing the result component. No privileges or user interaction are required, and the bounded consequence is disclosure of memory adjacent to the buffer.
