CVE-2022-49011

Service interruption via leaked PCI device references

Published Oct 21, 2024 · Updated May 11, 2026

Resource leak in the Linux coretemp driver allows local users to interrupt service by exhausting PCI device references. The adjust_tjmax function obtains an Intel host-bridge reference with pci_get_domain_bus_and_slot but fails to call pci_dev_put on its return paths. Reachability requires the coretemp driver on applicable Intel hardware; the published record does not identify a safe attacker-controlled trigger.
