Local privilege escalation via vring_init bounds error
Published Oct 25, 2024 · Updated Oct 25, 2024
Out-of-bounds write in Google Android's Trusty component allows local users to escalate privileges through the Android kernel. The vring_init logic in external/headers/include/virtio/virtio_ring.h initializes a virtio ring with erroneous bounds and writes outside its intended buffer. Exploitation requires local access but no user interaction; successful memory corruption grants elevated privileges on an affected Pixel device.
