Описание
The int3 handler in the Linux kernel before 3.3 relies on a per-CPU debug stack, which allows local users to cause a denial of service (stack corruption and panic) via a crafted application that triggers certain lock contention. If there is contention on this lock then the task may schedule out. As the task is using a per CPU stack, and another task may come in and use the same stack, the stack can become corrupted and cause the kernel to panic.
