CVE-2026-89740

A flaw was found in the Linux kernel's serial: imx component. The imxuartprobe function publishes a device-managed allocated port in the imxuartports array before it is fully added. If the port addition fails or the port is removed, the entry in the array is not properly cleared, resulting in a...
