Linux Kernel QCOM QMP Combo PHY NULL Pointer Dereference Vulnerability on Runtime Resume

Vulnerability

A vulnerability in the Linux kernel's QCOM QMP Combo PHY driver can lead to a NULL pointer dereference during runtime resume. This issue arises on platforms like SC7180, which do not provide a PCS_USB offset. The vulnerability was introduced when support for a separate PCS_USB region was added, but the wrong base was used, causing the NULL dereference.

Impact

Exploitation of this vulnerability leads to a NULL pointer dereference, causing a crash or undefined behavior in the kernel.
