What to do
AI-suggested
A fix has been implemented in the Linux kernel to address this issue. Users and administrators should update to the fixed kernel version once available. No additional mitigation is indicated in the advisory.
Description
A vulnerability in the Linux kernel's PCI brcmstb driver was fixed to correct error handling after a call to regulator_bulk_get(). If regulator_bulk_get() returns an error and no regulators are created, the number of regulators must be set to zero to avoid a kernel panic during regulator_bulk_free() if the PCIe link fails. The fix also includes printing the error value for better diagnostics.
