Fix not verifiedIn Nintendo Mario Kart 8 Deluxe before 3.0.3, the LAN/LDN local multiplayer implementation allows a remote attacker to exploit a stack-based buffer overflow upon deserialization of session information via a malformed browse-reply packet, aka KartLANPwn. The victim is not required to join a game session with an attacker. The victim must open the "Wireless Play" (or "LAN Play") menu from the game's title screen, and an attacker nearby (LDN) or on the same LAN network as the victim can send a crafted reply packet to the victim's console. This enables a remote attacker to obtain complete denial-of-service on the game's process, or potentially, remote code execution on the victim's console. The issue is caused by incorrect use of the Nintendo Pia library,

Untrusted data can cross into a code-evaluation path and be interpreted as executable instructions.
An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may execute code or commands in the affected security context.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
CISA Vulnrichment records proof-of-concept exploitation in its SSVC data. BlackTree has not independently executed or validated exploit material.
CWE-94: Improper Control of Generation of Code ('Code Injection'). The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
