{"id":"DEBIAN-CVE-2022-48908","details":"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.","modified":"2026-09-01T16:05:29.335475242Z","published":"2024-08-22T02:15:05.247Z","upstream":["CVE-2022-48908"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-48908"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.16.14-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-48908.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.16.14-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-48908.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.16.14-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-48908.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
