The vulnerability is resolved by initializing the RSS lookup table during vport creation rather than at interface startup.

The Linux kernel's network stack contains a null pointer dereference vulnerability in message handling that could cause a denial of service when the msg_get_inq field is improperly written by the callee function. Local attackers with basic privileges can trigger this condition by reusing kernel-internal msghdr structures, resulting in system crashes or service interruption. A patch is available to prevent writes to this input field and eliminate the unsafe branching logic.

A patch is available that adds proper pointer validation before accessing port structures.

A null pointer dereference in the Linux kernel's idpf driver allows local attackers with user privileges to cause a denial of service by triggering improper netdevice state management during reset operations. The vulnerability occurs when the driver fails to properly detach and close network devices before deallocating vport resources, leaving pointers unprotected from concurrent callback access. A patch is available to resolve this issue by implementing proper device state synchronization during reset handling.
