7DescriptionCVE.org
A stack-based buffer overflow vulnerability in the Nintendo Switch local wireless networking functionality may allow an attacker within wireless range to execute arbitrary code using return-oriented programming (ROP) through crafted network traffic. This issue affects Nintendo Switch: before 23.0.0.
AnalysisAI
Stack-based buffer overflow (CWE-121) in the Nintendo Switch local wireless networking subsystem allows an adjacent unauthenticated attacker within wireless range to execute arbitrary code via a Return-Oriented Programming (ROP) chain embedded in crafted network traffic. All Nintendo Switch firmware versions prior to 23.0.0 are affected, and Nintendo has released version 23.0.0 as the remediation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target Nintendo Switch must have local wireless networking functionality active - this occurs when the device is in local play mode or scanning for nearby consoles, which is not the default idle state but a user-initiated mode. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 7.0 (AV:A/AC:L/AT:N/PR:N/UI:P) reflects an adjacent-network attack requiring no authentication and only passive user interaction - the device need only have local wireless active. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Nintendo Switch firmware to version 23.0.0 or later via System Settings > System > System Update; this is the vendor-released patch per the Nintendo security advisory at https://www.nintendo.com/security-advisories/en/index.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
