CVE-2026-64595

HID: hid-lenovo-go suffered a race where a 2 ms delayed work (cfg_setup) could run after hid_destroy_device() releases hdev. The fix mirrors hid-lenovo-go-s.c by calling cancel_delayed_work_sync() and draining go_cfg_setup at hid_go_cfg_remove(), with cancellation occurring before acquiring cfg_m...

CVE-2026-64594

The CVE affects the Linux kernel USB gadget subsystem (functionfs) and specifically f_fs. The bug occurs because ffs->reset_work is not initialized on all code paths; it is only initialized via INIT_WORK() in ffs_func_set_alt() and ffs_func_disable() under FFS_DEACTIVATED, and only after ffs_d...
