Detailed vulnerability description
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
The MSM QDSP6 audio driver (aka sound driver) for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to gain privileges or cause a denial of service (integer overflow, and buffer overflow or buffer over-read) via a crafted application that performs a (1) AUDIO_EFFECTS_WRITE or (2) AUDIO_EFFECTS_READ operation, aka Qualcomm internal bug CR1006609.
