Set the buffer type to IGC_TX_BUFFER_TYPE_SKB. The Linux kernel CVE team has assigned CVE-2026-64035 to this issue. Affected and fixed versions =========================== Issue introduced in 6.16 with commit 5422570c0010bb968738f9256eb2bf83e79b4d63 and fixed in 6.18.34 with commit 1f83545f432d106d5fc71d3997b2d382104ebcc4 Issue introduced in 6.16 with commit 5422570c0010bb968738f9256eb2bf83e79b4d63 and fixed in 7.0.11 with commit 1c8587bd025244aa52061f5ceecbf5e68a1063d9 Issue introduced in 6.16 with commit 5422570c0010bb968738f9256eb2bf83e79b4d63 and fixed in 7.1 with commit 5acc641e590e008caaed480ed9ffae47cf7ecbdf Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community.

Affected files ============== The file(s) affected by this issue are: drivers/net/ethernet/intel/igc/igc_tsn.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/1f83545f432d106d5fc71d3997b2d382104ebcc4 https://git.kernel.org/stable/c/1c8587bd025244aa52061f5ceecbf5e68a1063d9 https://git.kernel.org/stable/c/5acc641e590e008caaed480ed9ffae47cf7ecbdf
