IOCTL, or input\/output control, is a <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-25180-underprivileged-software-manipulates-gpu-system-calls-for-unauthorized-access\/\"  data-wpil-monitor-id=\"88744\">system call<\/a> for device-specific I\/O operations. A malicious actor could craft and send an IOCTL command with an overly large buffer that the Bluetooth host is not equipped to handle, causing <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-22435-critical-memory-corruption-vulnerability-leading-to-privilege-escalation\/\"  data-wpil-monitor-id=\"86269\">memory corruption<\/a>.
