Service interruption via malformed Wi-Fi ioctl
Published Sep 14, 2026 · Updated Sep 14, 2026
An out-of-bounds write in Samsung Electronics Exynos 1330 Firmware through 2025-12-18 allows remote attackers to interrupt service via Wi-Fi ioctl. The Wi-Fi interface device allocates an improper buffer size when processing a malformed ioctl command, allowing an out-of-bounds write. Exploitation requires access to the device's Wi-Fi interface; the published impact is denial of service through service interruption, with no evidence of data disclosure or code execution.
