原因说明填写请参考下方表格(注意：版本是否受影响和版本的原因说明必须对应，例如master版本分支受影响，那原因说明只能是受影响对应的原因之一!)：

分支状态	原因说明	使用场景
受影响	正常修复	受影响且需要修复（包含升级版本修复）的漏洞；受影响且已经修复的漏洞（历史修复PR也需要关联issue）；若因特殊原因无法修复，应修改原因说明为【不修复-特殊原因】，并在安委会备案相关情况。
受影响	暂不修复-漏洞仍在分析中	已关注到相关漏洞，正在处理，未明确漏洞影响和修复方案。
受影响	暂不修复-暂无解决方案或补丁	当前没有可用的修复或补救措施。【影响性分析】中应包含有关为什么没有修复或补救措施的详细说明、上游相关PR等。
受影响	不修复-超出修复范围	没有漏洞的修复计划。当版本停维、软件包宣布生命周期终止或弃用使用。
受影响	不修复-特殊原因导致不再修复	如存在其他特殊情况不修复相关漏洞，或评估后无法升级修复，应在openEuler社区安全委员会例会进行说明备案。【影响性分析】中应包含有关为什么不发布修复的详细说明、特殊情况还应有安委会会议纪要。
不受影响	不受影响-组件不存在	软件不受影响，因为易受攻击的组件不在产品中。
不受影响	不受影响-已有内置的内联控制或缓解措施	内置的内联控制或缓解措施可防止攻击者利用漏洞
不受影响	不受影响-漏洞代码不能被攻击者触发	易受攻击的组件存在，并且该组件包含易受攻击的代码。但是，易受攻击的代码的使用方式使得攻击者无法进行任何预期的攻击。
不受影响	不受影响-漏洞代码不在执行路径	易受影响的代码在执行过程中不可访问，包括产品的非预期状态。产品不使用也不执行的组件。
不受影响	不受影响-漏洞代码不存在	产品不受影响，因为漏洞背后的代码在产品中不存在。与component_not_present不同的是，有问题的组件存在，但由于某种原因（例如安全的编译器选项）使漏洞的特定代码不存在于组件中。

CVE-2026-23035

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: Pass netdev to mlx5e_destroy_netdev instead of priv

mlx5e_priv is an unstable structure that can be memset(0) if profile
attaching fails.

Pass netdev to mlx5e_destroy_netdev() to guarantee it will work on a
valid netdev.

On mlx5e_remove: Check validity of priv->profile, before attempting
to cleanup any resources that might be not there.

This fixes a kernel oops in mlx5e_remove when switchdev mode fails due
to change profile failure.
