DESCRIPTION:

which potentially can be exploited by malicious people to compromise
a vulnerable system.

The vulnerability is caused due to a race condition when W29N51.SYS
handles multiple beacon frames. This can be exploited to overwrite
certain kernel memory structures via sending multiple specially
crafted beacon frames to the wireless card.

Successful exploitation may allow execution of arbitrary code.

also be affected.
