Overview

CVE-2025-22095 is a medium-severity vulnerability. It was published on April 16, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

PCI: brcmstb: Fix error path after a call to regulator_bulk_get()

If the regulator_bulk_get() returns an error and no regulators

are created, we need to set their number to zero.

If we don't do this and the PCIe link up fails, a call to the

regulator_bulk_free() will result in a kernel panic.

While at it, print the error value, as we cannot return an error

upwards as the kernel will WARN() on an error from add_bus().
