Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw within the staging driver for rtl8723bs. Specifically, a memory leak exists in the rtw init cmd priv() function. If pcmdpriv->rsp allocated buf is allocated but fails, pcmdpriv->cmd allocated buf is not properly released. The patch addresses this by adding kfree(pcmdpriv->cmd allocated buf); to the error path within the rtw init cmd priv() function and simplifying the return logic. No runtime testing was performed due to the lack of a suitable device.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
