Pointer Arithmetic Flaw in Intel THC in Linux Kernel

CVE-2025-39818

What is CVE-2025-39818?

The Intel THC within the Linux kernel exhibits a vulnerability arising from improper pointer arithmetic, which may lead to critical system behavior such as kernel crashes and out-of-bounds memory access. This issue involves the handling of I2C register addresses, where the use of secondary pointers resulted in a KASAN report highlighting a slab-out-of-bounds situation. The problem has been rectified by implementing direct array indexing to enhance memory safety and prevent further crashes.
