Unlike a segmentation fault (which the OS can often kill as a process), a machine check exception is typically . The CPU cannot guarantee the integrity of its state. Consequently, the operating system’s default response to 0x12 is a kernel panic (Linux) or a Bug Check 0x124 (Windows: WHEA_UNCORRECTABLE_ERROR). The x64 Exception type 0x12, or Machine Check

The Intel and AMD architecture manuals specify that the Machine Check Exception corresponds to vector 18, and to properly service these exceptions, a trap gate must be added to the Interrupt Descriptor Table (IDT) pointing to a dedicated MCE handler.In the Linux kernel source code, this vector is explicitly defined as MCE_VECTOR with the value 0x12 , clearly showing the direct link between the exception number and the machine-check handling mechanism. This is distinct from typical software errors that

A Machine-Check Exception (MCE) is a hardware error that occurs when the central processing unit (CPU) detects a serious, internal problem. This is distinct from typical software errors that cause application crashes. An MCE indicates a physical problem with the computer's hardware, such as the processor itself, the memory (RAM), the input/output (I/O) devices, or the system bus that connects these components. Because it's a hardware-level failure, it cannot be resolved by software patches or driver updates alone.
