The Linux kernel is vulnerable to a local denial-of-service attack. By using a C program it is possible to trigger a floating point exception that puts the kernel into an unusable state. To execute this attack a malicious user needs shell access to the victim's machine. The severity of this bug is considered low because local denial-of- service attacks are hard to prevent in general. Additionally the bug is limited to x86 and x86_64 architecture.
