CVE-2020-14127Network attack vector

Remote service interruption via heap overflow

Published Jul 14, 2022 · Updated Aug 4, 2024

Heap overflow in Xiaomi Redmi K40 and Redmi Note 10 Pro MIUI before 2022.07.01 allows remote attackers to interrupt service. The advisory identifies a heap overflow but does not disclose the affected component, triggering input, or faulty allocation or bounds operation. Exploitation requires network reachability but no authentication or user interaction, and the documented consequence is service interruption rather than data access or modification.
