Description
A flaw was found in the Linux kernel's Thunderbolt subsystem. When handling communication responses, a failure to set up a configuration request—such as when the control channel is already shut down—causes the system to return an error without releasing allocated memory. A local user or repeated communication errors can trigger this condition, potentially resulting in a denial of service (DoS) through system memory exhaustion.
