Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - ice将 XDP RxQ frag_size 从 DMA 写入长度更改为 xdp.frame_sz XDP RxQ 信息中 frag_size 字段的唯一用户是 bpf_xdp_frags_increase_tail()。显然需要整个 buff 大小而不是 DMA 写入大小。ice 驱动程序配置中的不同假设导致负 tailroom。当使用 XDP_ADJUST_TAIL_GROW_MULTI_BUFF xskxceiver 测试并将数据包大小更改为 6912并将请求的偏移更改为极大的值例如 XSK_UMEM__MAX_FRAME_SIZE * 100时这允许触发内核错误。由于 ice 中 ZC 配置的其他 quirk在 ZC 模式中未观察到错误但 tailroom 增长在应该不会时仍然会失败。在 XDP RxQ 信息中使用填充队列缓冲区 truesize 而非 DMA 写入大小。通过使用新的帮助程序也修复 ZC 模式。 (CVE-2026-23377)
