Summary
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 'ci' is required. However, the definition of
'com20020pci_id_table' 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+0x18d/0x13e0 [com20020_pci]
[ 3.975181] Call Trace:
[ 3.976208] local_pci_probe+0x13f/0x210
[ 3.977248] pci_device_probe+0x34c/0x6d0
[ 3.977255] ? pci_uevent+0x470/0x470
[ 3.978265] really_probe+0x24c/0x8d0
[ 3.978273] __driver_probe_device+0x1b3/0x280
[ 3.979288] driver_probe_device+0x50/0x370
Fix this by checking whether the 'ci' is a null pointer first.
