CVE-2022-30711

Local privilege escalation via improper FeedsInfo validation

Published Jun 7, 2022 · Updated Aug 3, 2024

Improper input validation in FeedsInfo before SMR Jun-2022 Release 1 allows local users to escalate privileges on Samsung Mobile Devices. FeedsInfo accepts attacker-controlled input without the validation required to prevent privileged activity, but Samsung has not disclosed the input field or code path. The flaw requires local execution but no prior privileges or user interaction and can expose data, alter protected state, and interrupt device operation.
