  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nirqchip/gic-v2m: Prevent use after free of gicv2m_get_fwnode()\nWith ACPI in place, gicv2m_get_fwnode() is registered with the pci\nsubsystem as pci_msi_get_fwnode_cb(), which may get invoked at runtime\nduring a PCI host bridge probe. But, the call back is wrongly marked as\n__init, causing it to be freed, while being registered with the PCI\nsubsystem and could trigger:\nUnable to handle kernel paging request at virtual address ffff8000816c0400\ngicv2m_get_fwnode+0x0/0x58 (P)\npci_set_bus_msi_domain+0x74/0x88\npci_register_host_bridge+0x194/0x548\nThis is easily reproducible on a Juno board with ACPI boot.\nRetain the function for later use.", "A flaw was found in the Linux kernel's irqchip/gic-v2m component. This vulnerability allows a use-after-free condition via gicv2m_get_fwnode() being wrongly marked as __init, causing it to be freed while still registered with the PCI (Peripheral Component Interconnect) subsystem during a PCI host bridge probe." ],
  "statement" : "A use-after-free flaw was found in the Linux kernel irqchip/gic-v2m module during a PCI host bridge probe, where a privileged user (PR:H) may access a callback which is already freed with the PCI\nsubsystem leading to a DoS and kernel information leak problem.",
