CVE-2022-50645

Unspecified impact via leaked PCI device references

Published Dec 9, 2025 · Updated May 11, 2026

Resource leak in the Linux kernel allows attackers to cause unspecified impact via affected i10nm EDAC driver code. The pci_get_dev_wrapper() function calls pci_dev_get() after pci_get_domain_bus_and_slot() already increments the PCI device reference count and also fails to release that reference when pci_enable_device() returns an error. Public sources do not identify an attacker-controlled trigger or a concrete operational consequence beyond the leaked reference.
