A vulnerability in the Linux kernel's serial driver for imx UART ports was resolved. The issue involved improper serialization of the imx_uart_ports[] array lifetime, where a dangling pointer could remain after a failed port addition or removal. This allowed a sibling probe to register a shared console through a stale entry, potentially causing inconsistent or unintended behavior. The fix ensures the entry remains valid through removal and protects port addition and removal operations to prevent interleaving. Occupied slots are now rejected rather than overwritten during duplicate-line probes.
