CWE-1281Sequence of Processor Instructions Leads to Unexpected Behavior

Description

Specific combinations of processor instructions lead to undesirable behavior such as locking the processor until a hard reset performed.

[object Object]

Common consequences

• Integrity,Availability→Varies by Context

Potential mitigations

• Testing
  Implement a rigorous testing strategy that incorporates randomization to explore instruction sequences that are unlikely to appear in normal workloads in order to identify halt and catch fire instruction sequences.
• Patching and Maintenance
  Patch operating system to avoid running Halt and Catch Fire type sequences or to mitigate the damage caused by unexpected behavior. See [REF-1108].
