Description OSIDB Bzimport 2026-09-24 16:24:05 UTC
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.
