In the Linux kernel, the following vulnerability has been resolved:
PCI: microchip: Fix refcount leak in mc_pcie_init_irq_domains()
of_get_next_child() returns a node pointer with refcount incremented, so we
should use of_node_put() on it when we don't need it anymore.
mc_pcie_init_irq_domains() only calls of_node_put() in the normal path,
missing it in some error paths. Add missing of_node_put() to avoid
refcount leak.
CISA SSVCTrack at low or medium mission impact; Track or Attend at high (mission-essential systems).
A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.
Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
