In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wcd937x: fix a potential memory leak in wcd937xsoccodec_probe()
When sndsocdapmnewcontrols() or sndsocdapmaddroutes() fails, wcd937xsoccodecprobe() returns without releasing 'wcd937x->clshinfo', which is allocated by wcdclshctrlalloc. Add wcdclshctrlfree() to prevent potential memory leak.
