CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a NULL pointer dereference in the admv1013 driver property parsing logic when reading device properties during device initialization. A local user can provide crafted property values or trigger property read failures to cause a denial of service.

The issue occurs because a failed string property read leaves a string pointer uninitialized before it is compared.
