An incorrect read request flaw was found in the Infrared Transceiver USB driver in the Linux kernel. This issue occurs when a user attaches a malicious USB device. A local user could use this flaw to starve the resources, causing denial of service or potentially crashing the system.

Mitigation

To mitigate this issue, prevent the mceusb module from being loaded. Please see <https://access.redhat.com/solutions/41278> for information about how to blacklist a kernel module to prevent it from loading automatically.
