CVE-2026-57554

Summary

A memory corruption vulnerability exists when asynchronous threads access shared performance counter data simultaneously during FastRPC invocations, potentially allowing attackers to execute arbitrary code with high privileges.

Exploitability

Exploitation requires local access with user privileges and specific timing conditions to trigger simultaneous thread access during FastRPC operations, making it moderately difficult but not highly complex to exploit.

Blast radius

If exploited, this vulnerability could impact gaming platforms and network devices using Qualcomm's Snapdragon G1 Gen 2 and AR8031/AR8035 chipsets, potentially affecting a wide range of IoT and embedded systems.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to Snapdragon G1 Gen 2 firmware version 2.590 or later, or AR8031/AR8035 firmware version 2.590 or later as specified in the vendor advisory.
