Linux Kernel NULL Pointer Dereference Vulnerability in GPIB PCMCIA Driver

Vulnerability

A vulnerability in the Linux kernel's GPIB PCMCIA driver has been addressed, which involved a NULL pointer dereference leading to a system crash. This issue arose because the 'pcmcia_driver' structure was improperly initialized, causing a NULL pointer dereference when 'strcmp' was called from 'pcmcia_register_driver'. The vulnerability has been fixed by correctly initializing the 'name' field of the 'pcmcia_driver' structure.

Impact

Exploitation of this vulnerability could lead to a system crash due to a NULL pointer dereference.
