CVE-2026-72026

In the Linux kernel, the following vulnerability has been resolved:

irqchip/irq-riscv-imsic-early: Fix fwnode leak on state setup failure

imsic_early_acpi_init() allocates a firmware node before setting up the
IMSIC state. If imsic_setup_state() fails, the function returns without
freeing the allocated fwnode.

Free the fwnode and clear the global pointer on this error path, matching
the cleanup already done when imsic_early_probe() fails.
