Summary
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):
comm "systemd-udevd", pid 297, jiffies 4294898478 (age 194.484s)
hex dump (first 32 bytes):

Fix this by freeing socket_data too.
Tested on a Acer Travelmate 4002WLMi by manually binding/unbinding
the yenta_cardbus driver (yenta_socket).
