https://notcve.org/view.php?id=CVE-2021-47324
In the Linux kernel, the following vulnerability has been resolved: watchdog: Fix possible use-after-free in wdt_startup() This module's remove path calls del_timer(). However, that function does not wait until the timer handler finishes. This means that the timer handler may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling del_timer_sync(), which makes sure the timer handler has finished, and unable to re-schedule itself. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: perro guardián: soluciona el posible use after free en wdt_startup().
