CVE-2026-93265— PCI/pwrctrl: tc9563: Fix parsing the integrated Ethernet MAC Endpoint node

Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： PCI/pwrctrl: tc9563: 修复对集成以太网 MAC 端点节点（Endpoint node）的解析问题 DSP3 集成有一个以太网 MAC 端点，该端点拥有自己的配置寄存器集，用于配置诸如 ASPM 等设置。该端点设备具有两个物理功能（physical functions），且这两个功能共享相同的配置设置。 应改为解析 DSP3 下的端点节点，而非分别解析两个功能。此外，现有的解析逻辑还存在一个越界（OOB）问题：若分别解析两个功能，将导致访问超出 数组边界。

Vulnerability Title
PCI/pwrctrl: tc9563: Fix parsing the integrated Ethernet MAC Endpoint node
Source: CVE Program / CVE List V5
Vulnerability 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.
