The session index variable in PCM host voice audio driver initialized before PCM open, accessed during event callback from ADSP and reset during PCM close may lead to race condition between event callback - PCM close and reset session index causing memory corruption.
The product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer.
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
