Software vendor:
Qualcomm

The vulnerability allows a local application to escalate privileges on the system.

The vulnerability exists due to a use-after-free error in the Automotive Android OS when process shell memory is freed using IOCTL munmap call and process initialization is in progress. A local application can trigger a use-after-free error and execute arbitrary code with elevated privileges.
