Title
ACPICA: Add AML_NO_OPERAND_RESOLVE flag to Timer
Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPICA: Add AML_NO_OPERAND_RESOLVE flag to Timer
ACPICA commit 90310989a0790032f5a0140741ff09b545af4bc5
According to the ACPI specification 19.6.134, no argument is required to be passed for ASL Timer instruction. For taking care of no argument, AML_NO_OPERAND_RESOLVE flag is added to ASL Timer instruction opcode.
When ASL timer instruction interpreted by ACPI interpreter, getting error. After adding AML_NO_OPERAND_RESOLVE flag to ASL Timer instruction opcode, issue is not observed.
