Doc Text:	A flaw was found in the Linux kernel. Missing boundary checks within the ACPICA (ACPI Component Architecture) subsystem allow out-of-bounds memory access when parsing ACPI bytecode. An attacker capable of supplying malformed ACPI tables can trigger this vulnerability, leading to a kernel crash and a Denial of Service (DoS).	Story Points:	---

acpi_ps_peek_opcode() to prevent out-of-bounds access.
