In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Fix memory leak in margining
Memory for the usb4->margining needs to be relased for the upstream port
of the router as well, even though the debugfs directory gets released
with the router device removal. Fix this.
A flaw was found in the Thunderbolt module in the Linux kernel. The missing release of memory allocated for the margining for the upstream port of the router can cause a memory leak, potentially impacting system stability and resulting in a denial of service.
