CVE-2017-13183 · MEDIUM Severity

AV:L/AC:H/AU:N/C:C/I:C/A:C

In the OMXNodeInstance::useBuffer and IOMX::freeBuffer functions, there is a possible use after free due to a race condition if the user frees the buffer while it's being used in another thread. This could lead to a local elevation of privilege enabling code execution as a privileged process with no additional execution privileges needed. User interaction is needed for exploitation. Product: Android. Versions: 8.1. Android ID: A-38118127.
