Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
rocker: fix memory leak in rocker_world_port_post_fini()<br />
<br />
In rocker_world_port_pre_init(), rocker_port->wpriv is allocated with<br />
kzalloc(wops->port_priv_size, GFP_KERNEL). However, in<br />
rocker_world_port_post_fini(), the memory is only freed when<br />
wops->port_post_fini callback is set:<br />
<br />
if (!wops->port_post_fini)<br />
return;<br />
wops->port_post_fini(rocker_port);<br />
kfree(rocker_port->wpriv);<br />
<br />
Since rocker_ofdpa_ops does not implement port_post_fini callback<br />
(it is NULL), the wpriv memory allocated for each port is never freed<br />
when ports are removed. This leads to a memory leak of<br />
sizeof(struct ofdpa_port) bytes per port on every device removal.<br />
<br />
Fix this by always calling kfree(rocker_port->wpriv) regardless of<br />
whether the port_post_fini callback exists.
