New Intel PROSet drivers has memory consumption issues

DailyTech previously reported Intel’s Centrino wireless drivers have security flaws. Intel recently released updated drivers for the 2200BG, 2915ABG and 3945ABG series wireless adapters that address the security flaw. While the drivers address the security flaw it presents a new problem. This time around the new generic Intel PROSet 10.5 control panel with driver release 10.5.1.57 has a memory leak problem.

According to DailyTech reader "MercenaryForHire," the Intel S24EvMon wireless management service is having troubles releasing registry handles. This leads to massive memory consumption during regular operation. The steps to recreate the memory leak is quite simple and involves installing the generic Intel PROSet 10.5 control panel and 10.5.1.57 drivers, then monitoring open handles and monitor memory usage of the Intel S24EvMon service.

Our very own Brandon Hill was able to recreate the problem with the latest Intel PROSet driver and an Asus W5F notebook. Intel is well aware of the issue and places the blame on individual manufacturers, claiming individual OEMs modify the wireless cards for its own configuration and need to release specific driver updates. There’s no word on when or if Intel will address this issue, though DailyTech suggests using drivers from the notebook manufacturer.

Update 8/23/2006: Dell and HP branded driver releases 10.5.1.57 for the 3945ABG or 9.0.4.17 for the 2200BG/2915ABG are also affected.
