CVE-2026-68314
Description
A flaw was found in the Linux kernel's MCTP I3C network module. When the i3c_driver_register() function fails during module initialization, the system does not properly unregister notifiers and deallocate bus objects. This oversight leads to a memory leak, which could be exploited by a local attacker to cause a Denial of Service (DoS) due to resource exhaustion.
