CVE-2023-54201

CVE-2023-54201 (Linux kernel) concerns RDMA/efa resource deallocation order. The fix deallocates resources in reverse order of allocation when destroying QP/CQ to prevent underflow of a zeroed refcount if the device destroy fails. The vulnerability arises because the code decremented the refcount...
