1) Memory leak (CVE-ID: CVE-2026-23464)

The vulnerability allows a local attacker to cause a denial of service.

The vulnerability exists due to a memory leak in mpfs_sys_controller_probe() when probing the system controller device. A local attacker can trigger an error path that fails to free allocated memory to cause a denial of service.

This issue occurs if of_get_mtd_device_by_node() fails after memory for sys_controller has been allocated.
