Description

A flaw was found in the Linux kernel's libipw wireless network driver. This flaw allows an adjacent attacker within wireless network range to cause a Denial of Service (DoS) by crashing the system. By sending a specially crafted wireless packet, an attacker can trigger an out-of-bounds memory read because the driver fails to properly validate buffer boundaries before reading encryption key information.
