Memory corruption via unchecked FM Host buffer copy
Published Jun 6, 2023 · Updated Aug 3, 2024
Classic buffer overflow in Qualcomm Snapdragon FM Host firmware allows local users with high privileges to corrupt memory via oversized input. FM Host copies attacker-controlled input into a buffer without first checking that the destination can hold it. The flaw requires a local, highly privileged caller; Qualcomm has not disclosed the command path, destination buffer, or a narrower consequence.
