"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: cdns3: Fix NULL pointer dereference in cdns3_pci_probe\n\nThe Cadence USBSS controller is a two-function PCI device. The first\nprobed function allocates the driver data and stores it with\npci_set_drvdata(), while the second function reuses it via\npci_get_drvdata() when pci_is_enabled() reports that the first\nfunction has already been probed.\n\nWhen the second function is probed while the first one has been\nenabled but has not yet set its driver data, pci_get_drvdata()\nreturns NULL, and the subsequent wrap->devfn assignment dereferences\na NULL pointer and crashes the kernel.\nlogs:\nCall trace:\n cdns3_pci_probe+0xa4/0x300\n local_pci_probe+0x44/0xa8\n pci_call_probe+0x54/0x158\n pci_device_probe+0x84/0x100\n really_probe+0x184/0x3d0\n __driver_probe_device+0x80/0x178\n driver_probe_device+0x44/0xe8\n __driver_attach+0xec/0x1f8\n bus_for_each_dev+0x7c/0xe0\n driver_attach+0x28/0x38\n bus_add_driver+0x110/0x238\n driver_register+0x64/0x128\n __pci_register_driver+0x50/0x60\n cdns3_pci_driver_init+0x28/0x38\n do_one_initcall+0x5c/0x280\n do_initcalls+0x104/0x1d8\n kernel_init_freeable+0x140/0x218\n kernel_init+0x28/0x1f8\n ret_from_fork+0x10/0x20\n\nReturn -EPROBE_DEFER in this case so that probing is retried after\nthe first function has completed its probe."
