Description

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