CVE-2026-58927

The vulnerability is a Use-After-Free (UAF) in the EVS AIDL HAL, arising from a data race on an unsynchronized std::weak ptr within EvsEnumerator::openCamera(). Specifically, concurrent calls from a privileged UID (e.g., AID AUTOMOTIVE EVS) can cause a torn weak ptr state, leading to a virtual call through a freed object's vtable at cameraObj->getCameraInfo(&desc). This allows for potential arbitrary code execution within the hal evs default process.
