      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: storage: realtek_cr: fix use-after-free on disconnect\n\nrealtek_cr_destructor() calls timer_delete() before the chip containing\nthe timer is freed. The timer callback may still be running and can\nrearm itself, resulting in a use-after-free.\n\nUse timer_shutdown_sync() to wait for the callback and prevent further\nrearming. Do this unconditionally because ss_en may be changed after\nthe timer is armed.\n\nMove timer_setup() into init_realtek_cr() so the timer is initialized\nbefore any failure path can invoke the destructor.\n\nFound by static analysis."
