Background
The ASoC (Audio System on Chip) framework in the Linux Kernel provides support for audio drivers on various SoC platforms. The ti (Texas Instruments) j721e-evm is a development board based on the J721E SoC. This vulnerability affects the j721e-evm board and is related to refcount leaks in the j721e_soc_probe_* functions.
Vulnerability Detail
The vulnerability in the j721e-evm board's ASoC implementation leads to a refcount leak in the j721e_soc_probe_* functions. This leak can result in resource exhaustion and potential denial-of-service (DoS) conditions. An attacker could exploit this vulnerability to exhaust system resources, leading to system instability or crashes. The vulnerability was introduced in Linux Kernel version v5.9 and is fixed in version v5.17.14 by commit d748ff8fbb3a5296bddd586445dc692b079cbe3d.
