CVE-2019-19543 [HIGH] CWE-416 kernel: use-after-free in serial_ir_init_module() in drivers/media/rc/serial_ir.c
kernel: use-after-free in serial_ir_init_module() in drivers/media/rc/serial_ir.c
In the Linux kernel before 5.1.6, there is a use-after-free in serial_ir_init_module() in drivers/media/rc/serial_ir.c.
A flaw was found in the Linux kernel’s infrared serial module. An attacker could use this flaw to corrupt memory and possibly escalate privileges.
Mitigation: As the module will be auto-loaded when the relevant hardware is required, its use can be disabled by preventing the module from loading with the following instructions:
# echo "install serial_ir /bin/true" >> /etc/modprobe.d/disable-serial-ir.conf
The system will need to be restarted if the CIFS modules are loaded. In most circumstances, the CIFS kernel modules will be unable to be unloaded while any network interfaces are active an

This was fixed for Fedora with the 5.1.6 stable kernel update.

So, I'm rating this moderate, because:
:- only able to be triggered during the failure to load the module
:- triggerable only during the load of the module ( administrative privileges required).
This doesn't qualify for Z stream/EUS fixes but if you have hardw
