Description

 The Linux Kernel contains a flaw that may allow a local denial of service. The issue is triggered when a race condition occurs that allows an attacker to modify an argument of a copy operation after is has been validated, but before it is used. This may present a window of opportunity for an attacker to gain access to sensitive information stored in memory.
