In the Linux kernel, the following vulnerability has been resolved: HID: sony: fix UAF of ghl_poke_timer / ghl_urb at driver unbind For GHL (Guitar Hero Live) dongles, sony_probe() arms a periodic timer: ghl_magic_poke() (the timer callback) submits sc->ghl_urb, and the URB completion ghl_magic_poke_cb() re-arms the timer with mod_timer(). sony_remove() drained the timer with timer_delete_sync() and then freed the URB with usb_free_urb(): timer_delete_sync(&sc->ghl_poke_timer); usb_free_urb(sc->ghl_urb); timer_delete_sync() does not block re-arming, and while the URB is in flight the timer is not pending, so the sync delete is a no-op. A URB completion that runs after the delete re-arms the timer, and usb_free_urb() only drops a reference -- it does not kill an in-flight URB. sc is allocated with devm_kzalloc() and freed once sony_remove() returns, so the re-armed ghl_poke_timer (embedded in sc) then fires on freed memory, a use-after-free from timer softirq. This is a disconnect/rmmod race. Poison the URB first, then shut the timer down, before freeing the URB. usb_poison_urb() kills any in-flight URB and permanently rejects further submissions, so a poke timer that is still pending cannot re-submit the URB from ghl_magic_poke() in the window before timer_shutdown_sync() runs. usb_kill_urb() would not suffice: it only cancels the in-flight URB and leaves it submittable once it returns, so the pending timer could re-submit it and put a fresh URB in flight over the freed sc. timer_shutdown_sync() then drains any last callback and blocks re-arming. The probe error path is unaffected: it is only reached before the timer is armed. Reproduced under KASAN on next-20260710 via dummy_hcd + raw-gadget emulation of the GHL PS4 dongle (VID 0x1430 / PID 0x07bb): hid-sony binds and arms the poke timer, the poke URB is held in flight, the driver is unbound (freeing sc), then the URB is released. The completion re-arms the timer on the freed sc, and the re-armed timer fires ~8 s later: BUG: KASAN: slab-use-after-free in ghl_magic_poke+0x98/0xb0 Read of size 8 at addr ffff88810b02fd50 by task swapper/0/0 ghl_magic_poke+0x98/0xb0 call_timer_fn+0x35/0x2b0 __run_timers+0x69c/0x9a0 run_timer_softirq+0x173/0x2a0 Allocated by task 169: sony_probe Freed by task 338: devres_release_group <- hid_device_remove (sony_remove) Found by 0sec (https://0sec.ai) using automated source analysis.
