CVE-2025-21934
In the Linux kernel, the following vulnerability has been resolved: rapidio: fix an API misues when rio_add_net() fails rio_add_net() calls device_register() and fails when device_register() fails.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.21%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: rapidio: fix an API misues when rio_add_net() fails rio_add_net() calls device_register() and fails when device_register() fails. Thus, put_device() should be used rather than kfree(). Add "mport->net = NULL;" to avoid a use after free issue.
