Security researchers recently rang a warning alert that the Linux Wi-Fi driver is riddled with a major flaw, which is capable of potentially enabling a hacker to intercept a laptop. The problem is said to be so threatening that the attack could come about even while the user is not on a Wi-Fi network. Experts think that this is the first remotely executable Wi-Fi bug of its type and particularly has an effect on the MadWi-Fi Linux kernel device driver for Atheros-based Wi-Fi chipsets.
Laurent Butti, a researcher from France Telecom Orange claimed to have spotted this vulnerability and released the related info at the previous month’s Black Hat conference in Amsterdam. He said:
You may be vulnerable if you do not manually patch your MadWi-Fi driver. He did share the trouble with the designers of the MadWi-Fi Linux kernel device driver who have now let loose a patch for the exaggerated users.
Butti maintained that the kernel stack-overflow worm is said to allow an attacker to sprint nasty code, and is able to be utilized even though the system is not actively on a Wi-Fi network. Butti said to have made use of fuzzing techniques displayed by David Maynor and Johnny Cache Jon Ellch at previous year’s Black Hat USA conference, and earlier- compromised on Windows and Macintosh systems.
