Because the weakness resides in the kernel\u2011mode Wi\u2011Fi driver, any device running the affected hardware and firmware is potentially vulnerable. No specific firmware revision numbers are provided, so all firmware on those processor lines should be considered at risk until an official fix is available.", "description_and_impact": "A buffer overflow flaw has been identified in Samsung Exynos Wi\u2011Fi drivers, triggered by malformed NL80211 vendor commands sent via a specific ioctl message. The overflow can overwrite adjacent memory, potentially allowing an attacker to execute arbitrary code on the device, granting full control and compromising confidentiality, integrity, and availability. The CVSS score of 9.8 reflects the extreme severity of this vulnerability.", "risk_and_exploitability": "The CVSS score of 9.8 indicates a high potential impact, while the EPSS score below 1% suggests a low current likelihood of exploitation. The vulnerability is not listed in the CISA KEV catalog, implying no publicly released exploit yet. Attackers would likely need to send a crafted NL80211 message to the device\u2019s Wi\u2011Fi interface, which could be achieved from an adjacent wireless network or by compromising the device locally. Thus the risk is moderate to high for devices that are accessible to attackers, especially when Wi\u2011Fi is enabled."}}}}, "created": "2026-04-08T19:38:39.818912+00:00", "updated": "2026-04-10T09:41:48.846952+00:00", "vendors": ["samsung", "samsung$PRODUCT$exynos"]}
