Description

A flaw was found in the Linux kernel's Intelligent Platform Management Interface (IPMI) SSIF (SMBus System Interface) driver. If an error occurs after a kernel thread (kthread) is created but before the main IPMI code initializes the SSIF interface, the kthread may not be properly stopped. This could lead to resource exhaustion or system instability, potentially resulting in a Denial of Service (DoS).

Mitigation

No mitigation is specified in collected source.
