Details

In the Linux kernel, the following vulnerability has been resolved:

rapidio: replace rio_free_net() with kfree() in rio_scan_alloc_net()

When idtab allocation fails, net is not registered with rio_add_net() yet, so kfree(net) is sufficient to release the memory. Set mport->net to NULL to avoid dangling pointer.

Severity
5.5 (Medium)
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
