Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: intel-thc-hid: intel-quicki2c: Fix ACPI dsd ICRS/ISUB length
The QuickI2C ACPI _DSD methods return ICRS and ISUB data with a
trailing byte, making the actual length is one more byte than the
structs defined.
It caused stack-out-of-bounds and kernel crash:

Adding reserved padding to quicki2c_subip_acpi_parameter/config.
