CVE-2022-50645: EDAC/i10nm: fix refcount leak in pci_get_dev_wrapper()

In the Linux kernel, the following vulnerability has been resolved: EDAC/i10nm: fix refcount leak in pci_get_dev_wrapper() As the comment of pci_get_domain_bus_and_slot() says, it returns a PCI device with refcount incremented, so it doesn't need to call an extra pci_dev_get() in pci_get_dev_wrapper(), and the PCI device needs to be put in the error path.

Security readout for executives and security teams

Plain-English summary

CVE-2022-50645 is a Linux kernel issue in the EDAC i10nm memory error reporting driver. The bug leaks a PCI device reference count in certain code paths. Public sources do not provide a CVSS score, business impact rating, or evidence of exploitation.

Executive priority

Handle through normal kernel patch management unless the environment heavily depends on affected hardware monitoring paths. There is no cited evidence of exploitation or severe impact, but kernel defects should still be remediated during supported maintenance windows.

Technical view

The fix removes an unnecessary pci_dev_get() after pci_get_domain_bus_and_slot(), which already returns a PCI device with an incremented refcount. It also ensures the PCI device is released on the error path. The issue is in EDAC/i10nm pci_get_dev_wrapper().

Likely exposure

Exposure appears limited to Linux systems running affected kernel versions with the EDAC/i10nm driver relevant to the hardware platform. The source lists Linux as affected, but does not provide complete distribution package mapping or a CVSS score.

Exploitation context

No source in the provided bundle states active exploitation, public exploit availability, or remote exploitability. CISA KEV status is false. Treat this as a kernel maintenance vulnerability unless vendor guidance indicates higher operational risk.

Researcher notes

Evidence is sparse: no CWE, CVSS, exploit status, or detailed impact is provided. The vulnerability is described as a refcount leak fix in EDAC/i10nm. Review the stable commits and downstream backports to determine exact affected and fixed kernel package versions.

Mitigation direction

  • Check Linux distribution advisories for CVE-2022-50645.
  • Update to a vendor-supported kernel containing the referenced stable fixes.
  • Prioritize systems using Intel i10nm EDAC functionality.
  • If patch timing is unclear, ask the vendor for affected package mapping.

Validation and detection

  • Inventory kernel versions across Linux servers and appliances.
  • Check whether EDAC/i10nm is present and relevant to hardware.
  • Compare installed kernel builds against distribution advisories.
  • Confirm the kernel includes one of the referenced stable commits.
