+ <h1>Problem Description:</h1>
+ <p>If a General Protection Fault happens on a FreeBSD/amd64
+ system while it is returning from an interrupt, trap or
+ system call, the swapgs CPU instruction may be called one
+ extra time when it should not resulting in userland and
+ kernel state being mixed.</p>
+ <h1>Impact:</h1>
+ <p>A local attacker can by causing a General Protection Fault
+ while the kernel is returning from an interrupt, trap or
+ system call while manipulating stack frames and, run
+ arbitrary code with kernel privileges.</p>
+ <p>The vulnerability can be used to gain kernel / supervisor
+ privilege. This can for example be used by normal users to
+ gain root privileges, to break out of jails, or bypass
+ Mandatory Access Control (MAC) restrictions.</p>
+ <h1>Workaround:</h1>
+ <p>No workaround is available, but only systems running the 64
+ bit FreeSD/amd64 kernels are vulnerable.</p>
+ <p>Systems with 64 bit capable CPUs, but running the 32 bit
+ FreeBSD/i386 kernel are not vulnerable.</p>
