Description
In the Linux kernel, the following vulnerability has been resolved:
PCI/pwrctrl: tc9563: Fix parsing the integrated Ethernet MAC Endpoint node
DSP3 has an integrated Ethernet MAC Endpoint which has its own set of config registers for configuring settings such as ASPM. The Endpoint device has two physical functions and those two functions share the same settings.
Parse the Endpoint node under DSP3 instead of parsing both functions. The existing parsing logic also has one OOB issue as parsing both functions will result in accessing past the tc9563_pwrctrl->cfg array.
