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: kernel: BUG: KASAN: stack-out-of-bounds in quicki2c_acpi_get_dsd_property.constprop.0+0x111/0x1b0 [intel_quicki2c] kernel: Write of size 12 at addr ffff888106d1f900 by task kworker/u33:2/75 kernel: kernel: CPU: 3 UID: 0 PID: 75 Comm: kworker/u33:2 Not tainted 6.16.0+ #3 PREEMPT(voluntary) kernel: Workqueue: async async_run_entry_fn kernel: Call Trace: kernel: <TASK> kernel: dump_stack_lvl+0x76/0xa0 kernel: print_report+0xd1/0x660 kernel: ? __pfx__raw_spin_lock_irqsave+0x10/0x10 kernel: ? __kasan_slab_free+0x5d/0x80 kernel: ? kasan_addr_to_slab+0xd/0xb0 kernel: kasan_report+0xe1/0x120 kernel: ? quicki2c_acpi_get_dsd_property.constprop.0+0x111/0x1b0 [intel_quicki2c] kernel: ? quicki2c_acpi_get_dsd_property.constprop.0+0x111/0x1b0 [intel_quicki2c] kernel: kasan_check_range+0x11c/0x200 kernel: __asan_memcpy+0x3b/0x80 kernel: quicki2c_acpi_get_dsd_property.constprop.0+0x111/0x1b0 [intel_quicki2c] kernel: ? __pfx_quicki2c_acpi_get_dsd_property.constprop.0+0x10/0x10 [intel_quicki2c] kernel: quicki2c_get_acpi_resources+0x237/0x730 [intel_quicki2c] [...] kernel: </TASK> kernel: kernel: The buggy address belongs to stack of task kworker/u33:2/75 kernel: and is located at offset 48 in frame: kernel: quicki2c_get_acpi_resources+0x0/0x730 [intel_quicki2c] kernel: kernel: This frame has 3 objects: kernel: [32, 36) 'hid_desc_addr' kernel: [48, 59) 'i2c_param' kernel: [80, 224) 'i2c_config' ACPI DSD methods return: \_SB.PC00.THC0.ICRS Buffer 000000003fdc947b 001 Len 0C = 0A 00 80 1A 06 00 00 00 00 00 00 00 \_SB.PC00.THC0.ISUB Buffer 00000000f2fcbdc4 001 Len 91 = 00 00 00 00 00 00 00 00 00 00 00 00 Adding reserved padding to quicki2c_subip_acpi_parameter/config.
