In the Linux kernel, the following vulnerability has been resolved:

pcmcia: rsrc_nonstatic: Fix memory leak in nonstatic_release_resource_db()

When nonstatic_release_resource_db() frees all resources associated
with an PCMCIA socket, it forgets to free socket_data too, causing
a memory leak observable with kmemleak:

unreferenced object 0xc28d1000 (size 64):

Fix this by freeing socket_data too.

Tested on a Acer Travelmate 4002WLMi by manually binding/unbinding
the yenta_cardbus driver (yenta_socket).
