Detailsinfo

A vulnerability was found in NetBSD 2.0/2.1/3.0/3.0.1 (Operating System). It has been classified as problematic. This affects some unknown functionality of the component Filesystem. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
