CVE-2020-11204

Memory corruption and disclosure via unchecked MSG parameters

Published Feb 22, 2021 · Updated Aug 4, 2024

Improper input validation in Qualcomm Snapdragon IPC allows local users to corrupt memory or disclose information through shared MSG RAM. The affected closed-source subsystem reads parameters from shared MSG RAM without checking validity or enforcing boundary compliance. Exploitation requires low-privileged local access and no user interaction; public records do not identify the specific IPC function or resulting memory operation.
