CVE-2022-48973

Resource leakage via unreleased PCI device references

Published Oct 21, 2024 · Updated May 11, 2026

Resource management error in the amd8111 GPIO driver in Linux 3.6 and later allows attackers to cause unspecified impact via driver lifecycle operations. The probe loop exits while retaining the current pci_dev reference, and amd_gpio_exit likewise omits pci_dev_put for the stored device. Reachability requires the amd8111 driver to traverse the affected PCI enumeration or exit path; the public record establishes retained references but specifies no resulting crash or exhaustion.
