NULL pointer dereference in IP socket options processing of the Networking Stack in QNX Software Development Platform (SDP) version(s) 7.1 and 7.0 could allow an attacker with local access to cause a denial-of-service condition in the context of the Networking Stack process.
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.
