In the Linux kernel, the following vulnerability has been resolved:
HID: intel-thc-hid: intel-thc: Fix incorrect pointer arithmetic in I2C regs save
Improper use of secondary pointer (&dev->i2c_subip_regs) caused kernel crash and out-of-bounds error:
BUG: KASAN: slab-out-of-bounds in _regmap_bulk_read+0x449/0x510 Write of size 4 at addr ffff888136005dc0 by task kworker/u33:5/5107

Replaced with direct array indexing (&dev->i2c_subip_regs[i]) to ensure safe memory access.
