Description OSIDB Bzimport 2026-08-15 06:37:43 UTC 
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().
