medium Tenable Cloud Security Plugin ID 469395

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Initialize re_id before
 removal registration rpcrdma_create_id() registers ep->re_rn with the rpcrdma ib_client before returning
 the new rdma_cm_id to rpcrdma_ep_create(). However rpcrdma_ep_create() currently stores that pointer in
 ep->re_id only after rpcrdma_create_id() returns. A local administrator can race an NFS/RDMA mount against
 RDMA device removal. If rpcrdma_remove_one() observes the just-registered notification before
 rpcrdma_ep_create() assigns ep->re_id, rpcrdma_ep_removal_done() calls
 trace_xprtrdma_device_removal(NULL). The tracepoint dereferences id->device->name and copies
 id->route.addr.dst_addr, so the callback can crash the kernel with a NULL pointer dereference. Store the
 rdma_cm_id in ep->re_id immediately before publishing ep->re_rn. The existing error path still destroys
 the id directly if registration fails; ep is then freed by the caller without using ep->re_id. Remove the
 later duplicate assignment in rpcrdma_ep_create(). (CVE-2026-72468)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
