Details
The method PVRSRVBridgeTLDiscoverStreams allocates puiStreamsInt on the heap, fills the contents of the buffer via TLServerDiscoverStreamsKM, and then copies the buffer to userspace. The method TLServerDiscoverStreamsKM may fail for several reasons including invalid sizes. If this method fails the buffer will be left uninitialized and despite the error will still be copied to userspace. Kernel leak of uninitialized heap data with no privs required.Product: AndroidVersions: Android SoCAndroid ID: A-236838960
