Background
The ASoC (Audio System on Chip) framework in the Linux Kernel provides support for audio drivers and codecs. The rx-macro codec is one such component that handles audio playback. It includes an array that stores enumerated values for different audio types. This vulnerability affects versions of the Linux Kernel starting from v5.12 and was fixed in v5.15.33. The vulnerability allows an attacker to access the array out of bounds, potentially leading to memory corruption or other security issues.
Vulnerability Detail
The vulnerability arises from accessing the array out of bounds for an enum type in the rx-macro codec of the ASoC framework. By providing malicious input or triggering specific conditions, an attacker can exploit this vulnerability to access memory locations beyond the bounds of the array. This can result in memory corruption, crashes, or even arbitrary code execution. The impact and attack plausibility of this vulnerability have not been proven yet.
How To Fix
No fixed version is published for this vulnerability.
