CVE-2026-92524Hinoki check available

Resource exhaustion via missed interrupt allocation teardown

Published Sep 17, 2026 · Updated Sep 17, 2026

Resource leakage in Linux irqchip/gic-v3-its allows local users to exhaust kernel resources via failed interrupt allocation. The its_vpe_irq_domain_alloc() error path frees earlier interrupts but skips its_vpe_teardown() for the failing interrupt, retaining its resources. Exposure requires the VPE allocation path and an allocation failure; denial of service is reported, but a specific crash or hang is not documented.
