CVE-2023-1118

A use-after-free flaw was found in the Linux kernel's integrated infrared receiver/transceiver driver. This issue occurs when a user detaches a rc device. This could allow a local user to crash the system or potentially escalate their privileges on the system.

Because this vulnerability requires an attacker to either have physical access to a system with infrared receiver/transceiver hardware or requires a remote authenticated user to have knowledge about such hardware attached to the system and when it is disconnected, Red Hat assesses the impact of this vulnerability as Moderate.

This bug stems from an error in drivers/media/rc/ene_ir.c. This is no longer being built, as CONFIG_IR_ENE is no longer enabled in Red Hat Enterprise Linux 9.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

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