Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the MIPS: Octeon component of the Linux kernel. It involves the standard PCIe configuration read-write interface used to access the configuration space of peripheral PCIe devices after a PCIe link surprise down, which can generate a kernel panic caused by a "Data bus error". To protect the system, a PCIe link status check is necessary. When the PCIe link is down or in training, assigning a value of 0 to the configuration address can prevent read-write behavior to the configuration space of peripheral PCIe devices, thereby preventing kernel panic.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
