NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150700_53_90-default package and not the kernel-livepatch-6_4_0-150700_53_90-default package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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

rapidio: clear mport->net when rio_add_net() fails

rio_alloc_net() stores the newly allocated rio_net in mport->net before rio_scan_alloc_net() registers the device.

If rio_add_net() fails, rio_scan_alloc_net() drops the device reference with put_device(), which releases the rio_net through the device release callback. However, mport->net is left pointing at the freed object.

A later mport unregister path can then dereference the dangling mport->net pointer and may try to free the same rio_net again.

Clear mport->net in the rio_add_net() failure path, matching the cleanup done for the destID table allocation failure path.
