high Tenable Cloud Security Plugin ID 461537

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: RDMA/rxe: Fix null deref on
 srq->rq.queue after resize failure A NULL pointer dereference can occur in rxe_srq_chk_attr() when
 ibv_modify_srq() is invoked twice in succession under certain error conditions. The first call may fail in
 rxe_queue_resize(), which leads rxe_srq_from_attr() to set srq->rq.queue = NULL. The second call then
 triggers a crash (null deref) when accessing srq->rq.queue->buf->index_mask. Call Trace: <TASK>
