Editing General protection fault (section)

===Miscellaneous===
Other causes of general protection faults are:
* attempting to access an interrupt/exception handler from [[virtual 8086 mode]] when the handler's code segment descriptor [[privilege level]] (DPL) is greater than zero
* attempting to write a one into the reserved bits of [[control register|CR4]]
* attempting to execute [[privilege (computing)|privileged]] instructions when the current privilege level (CPL) is not zero
* attempting to execute a single instruction with a length greater than 15 bytes (possibly by prepending the instruction with superfluous prefixes)<ref>{{cite web|url=https://xem.github.io/minix86/manual/intel-x86-and-64-manual-vol3/o_fe12b1e2a880e0ce-223.html|title=Page 223|access-date=2023-09-24}}</ref>
* writing to a reserved bit in an [[model-specific register|MSR]] instruction
* accessing a gate containing a null segment selector
* executing a software interrupt when the CPL is greater than the DPL set for the interrupt gate
* the segment selector in a call, interrupt or trap gate does not point to a code segment
* violating privilege rules
* enabling paging whilst disabling protection
* referencing the interrupt descriptor table following an interrupt or exception that is not an interrupt, trap, or a task gate
* Legacy [[Streaming SIMD Extensions|SSE]]: Memory operand is not 16-byte aligned.
