  script_tag(name:"insight", value:"Multiple flaws exist due to:

  - Lazy FP state restore instead of eager save and restore of the state upon a
    context switch. Lazy restored states are potentially vulnerable to exploits
    where one process may infer register values of other processes through a
    speculative execution side channel that infers their value.

  - A memory corruption issue due to poor memory handling.");
