CVE-2026-89740

CVE-2026-89740 is a dangling pointer vulnerability in the Linux kernel's imx UART (serial) driver . imx_uart_probe() publishes its devm-allocated port in the imx_uart_ports[] table before calling uart_add_one_port(), but the entry is not cleared on failure or after removal, leaving a stale pointe...

CVE-2026-89740 serial: imx: serialize imx_uart_ports[] lifetime

In the Linux kernel, the following vulnerability has been resolved: serial: imx: serialize imxuartports lifetime imxuartprobe publishes its devm-allocated port in imxuartports before uartaddoneport because console setup uses the table. The entry is not cleared when adding the port fails or after...
