CVE-2026-72499
RDMA/bnxt_re: Free CQ toggle page after firmware teardown
Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Free CQ toggle page after firmware teardown Free the toggle page only after firmware teardown completes so that an NQ interrupt arriving during bnxt_qplib_destroy_cq() won't write the toggle value to an already-freed page. Move free_page() after bnxt_qplib_destroy_cq.
