In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v2m: Prevent use after free of gicv2m_get_fwnode()
With ACPI in place, gicv2m_get_fwnode() is registered with the pci
subsystem as pci_msi_get_fwnode_cb(), which may get invoked at runtime
during a PCI host bridge probe. But, the call back is wrongly marked as
__init, causing it to be freed, while being registered with the PCI
subsystem and could trigger:
Unable to handle kernel paging request at virtual address ffff8000816c0400
gicv2m_get_fwnode+0x0/0x58 (P)
pci_set_bus_msi_domain+0x74/0x88
pci_register_host_bridge+0x194/0x548
This is easily reproducible on a Juno board with ACPI boot.
Retain the function for later use.
