CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of the PCI power control for the tc9563 integrated Ethernet MAC Endpoint, where improper parsing of configuration registers can lead to out-of-bounds access. This flaw could potentially allow an attacker to manipulate device settings, leading to instability or exploitation of the affected system. Linux system administrators and developers working with affected kernel versions should prioritize addressing this issue to maintain system integrity and security.
Original NVD 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.
