Peter Anvin" <hpa@...or.com>, Kees Cook <kees.cook@...onical.com> Subject: [BUG] broken ebba638ae723d8a8fc2f7abce5ec18b688b791d7 Hi, ebba638ae723d8a8fc2f7abce5ec18b688b791d7 x86, cpu: Call verify_cpu during 32bit CPU startup look buggy. It add a call to verify_cpu, but we never set the stack before (I check with qemu + gdbserver that sp is random when doing cpu hotplug). This mean do randomly corrupt the memory.
