The max supported value is 64K. Adding a max and min check and fail if user supplied value is more than the max supported and zero. The Linux kernel CVE team has assigned CVE-2026-72497 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/infiniband/hw/bnxt_re/ib_verbs.c drivers/infiniband/hw/bnxt_re/qplib_sp.h 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/a59d815cbe667929b693b5fa6716a074e6a31c5b https://git.kernel.org/stable/c/dc95931b7e1326dacae547874bf38c092e5960d8
