"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: arcnet: com20020: Fix null-ptr-deref in com20020pci_probe()\n\nDuring driver initialization, the pointer of card info, i.e. the\nvariable 'ci' is required. However, the definition of\n'com20020pci_id_table' reveals that this field is empty for some\ndevices, which will cause null pointer dereference when initializing\nthese devices.\n\nThe following log reveals it:\n\n[ 3.973806] KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f]\n[ 3.973819] RIP: 0010:com20020pci_probe+0x18d/0x13e0 [com20020_pci]\n[ 3.975181] Call Trace:\n[ 3.976208] local_pci_probe+0x13f/0x210\n[ 3.977248] pci_device_probe+0x34c/0x6d0\n[ 3.977255] ? pci_uevent+0x470/0x470\n[ 3.978265] really_probe+0x24c/0x8d0\n[ 3.978273] __driver_probe_device+0x1b3/0x280\n[ 3.979288] driver_probe_device+0x50/0x370\n\nFix this by checking whether the 'ci' is a null pointer first."
