CVE-2025-68379
Description
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:
