CVE-2024-9413Network attack vector

Memory corruption via transport error mishandling

Published Nov 13, 2024 · Updated Nov 27, 2024

Buffer overflow in Arm SCP-firmware 2.11.0 through 2.15.0 allows attackers controlling an Application Processor to corrupt SCP memory. The transport_message_handler function mishandles an error condition during AP-to-SCP transport processing, causing data to exceed its destination buffer. Reachability requires control of the Application Processor and interaction with the SCP transport path; Arm has not disclosed the exact post-overflow consequence.
