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.
[ tglx: Use a common cleanup path instead of copying code around ]
