A NULL pointer dereference issue was discovered in the Linux kernel in the MPTCP protocol when traversing the subflow list at disconnect time. A local user could use this flaw to potentially crash the system causing a denial of service.
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.
