Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： 网络子系统：devmem：防止 net_iov 与 page 类型的片段混合 在同一个 skb（socket 缓冲区）中，片段 backing 存储必须要么全部使用 net_iov，要么全部使用 page 类型，否则会导致协议栈后续处理时出现崩溃。因此，在 zerocopy_fill_skb_from_devmem() 函数中，禁止混合使用这两种类型的片段。
