Vulnerability from github – Published: 2026-04-22 15:31 – Updated: 2026-04-28 15:30

Details

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

RDMA/irdma: Initialize free_qp completion before using it

In irdma_create_qp, if ib_copy_to_udata fails, it will call irdma_destroy_qp to clean up which will attempt to wait on the free_qp completion, which is not initialized yet. Fix this by initializing the completion before the ib_copy_to_udata call.

Severity ?

5.5 (Medium)
