Description OSIDB Bzimport 2025-06-18 12:06:18 UTC 
In the Linux kernel, the following vulnerability has been resolved:

RDMA/irdma: Fix a window for use-after-free

During a destroy CQ an interrupt may cause processing of a CQE after CQ
resources are freed by irdma_cq_free_rsrc(). Fix this by moving the call
to irdma_cq_free_rsrc() after the irdma_sc_cleanup_ceqes(), which is
called under the cq_lock.
