CVE-2026-80942Hinoki check available

Kernel memory leak via incomplete initialization cleanup

Published Sep 11, 2026 · Updated Sep 11, 2026

Memory leak in the Linux kernel 6.11 rtl8192du Wi-Fi driver allows attackers to consume kernel memory during failed device initialization. rtl92du_init_sw_vars() calls rtl92du_init_shared_data() but returns from later firmware-buffer allocation and firmware-request error paths without invoking rtl92du_deinit_shared_data() to free the shared allocations. The record does not establish that unprivileged users can trigger these paths or that the leak causes a crash or other service interruption.
