A vulnerability was found in Linux Kernel where, a memory leak in the i2400m_op_rfkill_sw_toggle() function in drivers/net/wimax/i2400m/op-rfkill.c allows attackers to cause a denial of service (memory consumption).
Created kernel tracking bugs for this issue:
Affects: fedora-all [bug 1775005]
This was fixed for Fedora with the 5.3.11 stable kernel update.
As the i2400m module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions:
# echo "install i2400m /bin/true" >> /etc/modprobe.d/disable-i2400m.conf
The system will need to be restarted if the i2400m module is already loaded. In most circumstances, the i2400m kernel module will be unable to be unloaded while the device is in use. If the system requires this module to work correctly, this mitigation may not be suitable.
