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

atm: iphase: fix possible use-after-free in ia_module_exit()
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.
A use-after-free flaw was found in the Linux kernel’s ATM networking card driver in how a user unloads the driver's module. This flaw allows a local user to crash the system.
Statement: The bug happens during module unloadi
