CVE-2026-68418

A flaw was found in the RDMA/irdma component of the Linux kernel. A local user could exploit this vulnerability by providing a zero value for userwqebufs during the creation of a Queue Pair QP. This action leads to a null pointer dereference, which can cause the system to crash, resulting in a...

CVE-2026-68417

A flaw was found in the Linux kernel's RDMA/siw component. The siwcreateqp function prematurely publishes a Queue Pair QP before its complete initialization. This allows a Queue Pair Number QPN lookup to access a QP that is still under construction, potentially leading to unexpected behavior or...

CVE-2026-68419

A flaw was found in the Linux kernel's RDMA/irdma component. A local user could exploit this by attempting to re-register specific memory regions Queue Pair, Completion Queue, or Shared Receive Queue objects that are not intended for re-registration. This could lead to an invalid operation being...
