Samsung Exynos Wi-Fi Driver NL80211 Handling

Buffer overflow in Samsung Exynos Wi-Fi drivers (980, 850, 1280, 1330, 1380, 1480, 1580, W920, W930, W1000) allows unauthenticated remote attackers to execute arbitrary code with high integrity/confidentiality impact through malformed NL80211 vendor command ioctl messages. Improper input validation enables network-accessible exploitation without user interaction. CVSS 9.8 critical severity. No public exploit identified at time of analysis.

Buffer overflow in Samsung Exynos Wi-Fi driver (980, 850, 1280, 1330, 1380, 1480, 1580, W920, W930, W1000) allows unauthenticated remote code execution via malformed NL80211 vendor command ioctl message. Incorrect handling of vendor-specific wireless configuration commands enables network-based memory corruption. CVSS 9.8 critical severity reflects network attack vector requiring no authentication or user interaction. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.01%).
