Linux Kernel Refcount Leak Vulnerability in ASoC MXS Component

Vulnerability

A refcount leak vulnerability has been identified in the ASoC MXS component of the Linux kernel. The issue arises in the 'mxs_sgtl5000_probe' function, which improperly handles error conditions. Specifically, when the 'codec_np' pointer is NULL while 'saif_np[0]' and 'saif_np[1]' are not NULL, the function fails to release the reference count of the regular pointers, leading to a memory leak.

Impact

Exploitation of this vulnerability causes a memory leak, which can lead to increased memory usage and potential degradation of system performance over time.
