Background
The ASoC (Audio System on Chip) is a subsystem in the Linux Kernel that provides support for audio devices integrated into SoCs (System on Chips). It allows for the configuration and control of audio-related operations on these devices. One of the functions in ASoC, snd_soc_put_xr_sx(), is responsible for handling input values for certain audio operations. However, this function does not properly validate the input values, which can lead to out of bounds access and potential security vulnerabilities.
Vulnerability Detail
The vulnerability in snd_soc_put_xr_sx() arises from the lack of proper bounds checking on input values. An attacker could exploit this by providing malicious input values that go beyond the expected range, potentially leading to memory corruption or privilege escalation. The impact and attack plausibility of this vulnerability have not been proven yet. It is important to note that this vulnerability has been fixed in the Linux Kernel version v4.9.300 by commit 17e16a66b4f9a310713d8599e6e1ca4a0c9fd28c.
How To Fix
