If Relaxed Ordering (RO) is enabled, the zero padding may overwrite valid data in the next segment and corrupt the data. Older chips (P5 and older) do not automatically disable RO when EOP is enabled. On some ARM systems, data corruption was reported on 57508 (P5) chips with RO enabled. Always disable EOP on all chips on the AGG rings when TPA is enabled to fix the data corruption. The Linux kernel CVE team has assigned CVE-2026-74697 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/net/ethernet/broadcom/bnxt/bnxt.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/68c181af7cd1ca9cbf29acd95911073bfd3c6397 https://git.kernel.org/stable/c/7aee22a35978b44784612c156e358e375ddf5d16 https://git.kernel.org/stable/c/410da4428b1f47bf9a84bdc0bcaa089d73ba2048 https://git.kernel.org/stable/c/b61c4911204a0a2f900e538d64ceb608f6c9614d https://git.kernel.org/stable/c/aab3b5f4d8ec8598606ee011e219ef824ae25ca0 https://git.kernel.org/stable/c/c1962ab4645a914a91ff492735881150ddc8a79e https://git.kernel.org/stable/c/c3faf548a00f4c17100cc9204746975fa46a73b9
