BTW, I saw these lines in the oops message:
kernel: [3077010.856312] last sysfs file:
/sys/devices/system/cpu/cpu23/cache/index2/shared_cpu_map

does your program somehow read or write to this sysfs entry?

care to explain briefly what this program_t does?

IIRC, once there is kernel bug (or maybe more than one) than enable
user space to "implant" code in kernel space. In the same sense, it
would be no surprise that kernel stack could be wiped out.
