Move free_page() after bnxt_qplib_destroy_srq(). The Linux kernel CVE team has assigned CVE-2026-72500 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/infiniband/hw/bnxt_re/ib_verbs.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/104a7ff382a58a83cae018925e3574c784e8274c https://git.kernel.org/stable/c/0adcd67f3d6f84835be682da0153f57f5c2f8036 https://git.kernel.org/stable/c/131e2918b9b0529687e67e2e58047304027f095a
