Уязвимость функции HFC_cleanup() модуля drivers/isdn/hardware/mISDN/hfcpci.c - драйвера поддержки оборудования mISDN ядра операционной системы Linux, позволяющая нарушителю оказать воздействие на целостность и доступность защищаемой информации

In the Linux kernel, the following vulnerability has been resolved: mISDN: fix possible use-after-free in HFC_cleanup() 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.
