Описание
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: fix a potential memory leak in rtw_init_cmd_priv()
In rtw_init_cmd_priv(), if pcmdpriv->rsp_allocated_buf is allocated
in failure, then pcmdpriv->cmd_allocated_buf will be not properly
released. Besides, considering there are only two error paths and the
first one can directly return, so we do not need implicitly jump to the
exit tag to execute the error handler.
So this patch added kfree(pcmdpriv->cmd_allocated_buf); on the error
path to release the resource and simplified the return logic of
rtw_init_cmd_priv(). As there is no proper device to test with, no runtime
testing was performed.
