The kernel of Oracle Solaris contains a vulnerability in the code that handles UCODE_GET_VERSION IOCTL requests. The vulnerability allows a local unprivileged user the ability to panic a Solaris x86 Intel-based system (32-bit/64-bit mode) due to a NULL pointer dereference. The ability to panic a system is a type of Denial of Service (DoS). The issue can be triggered by sending a specially crafted IOCTL request to the kernel.
