  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: arcnet: com20020: Fix null-ptr-deref in com20020pci_probe()  During driver initialization, the pointer of card info, i.e. the variable \u0027ci\u0027 is required. However, the definition of \u0027com20020pci_id_table\u0027 reveals that this field is empty for some devices, which will cause null pointer dereference when initializing these devices.  The following log reveals it:  [    3.973806] KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f] [    3.973819] RIP: 0010:com20020pci_probe\u002B0x18d/0x13e0 [com20020_pci] [    3.975181] Call Trace: [    3.976208]  local_pci_probe\u002B0x13f/0x210 [    3.977248]  pci_device_probe\u002B0x34c/0x6d0 [    3.977255]  ? pci_uevent\u002B0x470/0x470 [    3.978265]  really_probe\u002B0x24c/0x8d0 [    3.978273]  __driver_probe_device\u002B0x1b3/0x280 [    3.979288]  driver_probe_device\u002B0x50/0x370  Fix this by checking whether the \u0027ci\u0027 is a null pointer first.",
