## Overview

In the Linux kernel, the following vulnerability has been resolved:

RDMA/bnxt_re: Free SRQ toggle page after firmware teardown

Free the toggle page only after firmware teardown completes so that
an NQ interrupt arriving during bnxt_qplib_destroy_srq() won't write
the toggle values to an already-freed page. Move free_page() after
bnxt_qplib_destroy_srq().

## Affected

- `Linux >= 181028a0d84cdcc7ac86d05cc49eaa416ce85c8b < 104a7ff382a58a83cae018925e3574c784e8274c`
- `Linux >= 181028a0d84cdcc7ac86d05cc49eaa416ce85c8b < 0adcd67f3d6f84835be682da0153f57f5c2f8036`
- `Linux >= 181028a0d84cdcc7ac86d05cc49eaa416ce85c8b < 131e2918b9b0529687e67e2e58047304027f095a`
- `Linux 6.12`
