CVE-2026-57554

Memory corruption via concurrent performance-counter access

Published Oct 6, 2026 · Updated Oct 6, 2026

Memory corruption in Qualcomm Snapdragon FastRPC allows attackers to corrupt shared performance-counter data during concurrent invocations. The FastRPC performance-counter path permits asynchronous invocation threads to access shared counter data simultaneously; the precise faulty operation has not been published. Triggering the issue requires overlapping FastRPC invocations on an affected device, while remote reachability and consequences beyond memory corruption remain undisclosed.
