CVE-2025-37836
In the Linux kernel, the following vulnerability has been resolved: PCI: Fix reference leak in pci_register_host_bridge() If device_register() fails, call put_device() to give up the reference to avoid a memory leak, per the comment at device_register().
Does this matter?
Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.
