Description
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. ============================================================= UBSAN: array-index-out-of-bounds in acpica/dswexec.c:401:12 index -1 is out of range for type 'union acpi_operand_object *[9]' CPU: 37 PID: 1678 Comm: cat Not tainted 6.0.0-dev-th500-6.0.y-1+bcf8c46459e407-generic-64k HW name: NVIDIA BIOS v1.1.1-d7acbfc-dirty 12/19/2022 Call trace: dump_backtrace+0xe0/0x130 show_stack+0x20/0x60 dump_stack_lvl+0x68/0x84 dump_stack+0x18/0x34 ubsan_epilogue+0x10/0x50 __ubsan_handle_out_of_bounds+0x80/0x90 acpi_ds_exec_end_op+0x1bc/0x6d8 acpi_ps_parse_loop+0x57c/0x618 acpi_ps_parse_aml+0x1e0/0x4b4 acpi_ps_execute_method+0x24c/0x2b8 acpi_ns_evaluate+0x3a8/0x4bc acpi_evaluate_object+0x15c/0x37c acpi_evaluate_integer+0x54/0x15c show_power+0x8c/0x12c [acpi_power_meter]

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability involves the Linux kernel's ACPICA component where the ASL Timer instruction did not properly handle the case when no argument is passed, which is allowed by the ACPI specification. This caused an error during interpretation of the ASL Timer instruction. The issue was fixed by adding the AML_NO_OPERAND_RESOLVE flag to the ASL Timer instruction opcode, preventing the error from occurring.


How can this vulnerability impact me? :

The vulnerability could cause errors or crashes in the ACPI interpreter within the Linux kernel when processing ASL Timer instructions without arguments, potentially affecting system stability or power management features.
