Local denial of service via unbounded allocation
Published Feb 3, 2026 · Updated Feb 3, 2026
Resource exhaustion in Samsung Exynos Wi-Fi drivers allows local users to exhaust kernel memory through a procfs write. The conn_log_event_burst_to_us write handler under /proc/driver/unifi0 allocates kernel memory without enforcing a bound on supplied input. Local access to the procfs node is required, and repeated or oversized writes consume kernel memory until device operation is interrupted.
