  3. CVE-2026-23464
In the Linux kernel, the following vulnerability has been resolved: soc: microchip: mpfs: Fix memory leak in mpfs_sys_controller_probe() In mpfs_sys_controller_probe(), if of_get_mtd_device_by_node() fails, the function returns immediately without freeing the allocated memory for sys_controller, leading to a memory leak. Fix this by jumping to the out_free label to ensure the memory is properly freed. Also, consolidate the error handling for the mbox_request_channel() failure case to use the same label.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: soc: microchip: mpfs: Corrección de fuga de memoria en mpfs_sys_controller_probe() En mpfs_sys_controller_probe(), si of_get_mtd_device_by_node() falla, la función retorna inmediatamente sin liberar la memoria asignada para sys_controller, lo que provoca una fuga de memoria. Esto se soluciona saltando a la etiqueta out_free para asegurar que la memoria se libere correctamente. Además, se consolida el manejo de errores para el caso de fallo de mbox_request_channel() para usar la misma etiqueta.
