Background
The ASoC (Audio System on Chip) framework in the Linux Kernel is responsible for managing audio devices on embedded systems. One of the supported audio codecs is the rt5645. This codec is commonly used in various devices, including smartphones, tablets, and laptops. The rt5645 codec provides features such as audio playback, recording, and audio signal processing. However, a vulnerability has been discovered in the rt5645 driver that could lead to erroneous cleanup order.
Vulnerability Detail
The vulnerability in the rt5645 driver arises from an incorrect cleanup order. When the driver is unloaded or encounters an error during initialization, certain resources may not be properly released, leading to potential memory leaks or other undefined behavior. An attacker with local access to the affected system could potentially exploit this vulnerability to gain elevated privileges or cause a denial-of-service condition. It is important to note that the impact and attack plausibility of this vulnerability have not been proven.
How To Fix
No fixed version is published for this vulnerability.
To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.18.3 or later. The fix for this issue was implemented in commit 453f0920ffc1a28e28ddb9c3cd5562472b2895b0. Updating the kernel will ensure that the erroneous cleanup order in the rt5645 driver is corrected.
