Summary
The acdb audio driver in the Linux kernel (as used in Qualcomm's Android contributions for MSM devices and other products) contains a stack-based buffer overflow in its ioctl handling. An attacker who can run an application with access to the driver's device node could exploit this to gain elevated privileges on the affected system.

Stack-based buffer overflow in the acdb_ioctl function in audio_acdb.c in the acdb audio driver for the Linux kernel 2.6.x and 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to gain privileges via an application that leverages /dev/msm_acdb access and provides a large size value in an ioctl argument.
