Vulnerability from github – Published: 2026-11-02 21:32 – Updated: 2026-11-02 21:32

Details

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.

CVE-2026-58927 (GCVE-0-2026-58927)

Vulnerability from cvelistv5 – Published: 2026-11-02 20:21 – Updated: 2026-11-02 20:21

Summary

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.
