medium Tenable Cloud Security Plugin ID 459340

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: smb: client: let smbd_destroy() call
 disable_work_sync(&info->post_send_credits_work) In smbd_destroy() we may destroy the memory so we better
 wait until post_send_credits_work is no longer pending and will never be started again. I actually just
 hit the case using rxe: WARNING: CPU: 0 PID: 138 at drivers/infiniband/sw/rxe/rxe_verbs.c:1032

 rdma_destroy_qp(). This happened because put_receive_buffer() was triggered by ib_drain_qp() and called:
 queue_work(info->workqueue, &info->post_send_credits_work); (CVE-2025-39932)
