In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
usb: storage: realtek_cr: fix use-after-free on disconnect<\/p>\n
realtek_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.<\/p>\n
Use 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.<\/p>\n
Move timer_setup() into init_realtek_cr() so the timer is initialized
\nbefore any failure path can invoke the destructor.<\/p>\n
