Published Nov 21, 2024 · Updated Nov 21, 2024

DoIPConnection::reactOnReceivedTcpMessage leaves routedClientAddress unallocated when command 0x8001 arrives before routing activation, then dereferences it. The sequence bypasses the normal allocation path and interrupts only the hosting process; no data disclosure or modification is reported.
