CVE-2023-53433

一、漏洞信息
 漏洞编号：[CVE-2023-53433](https://nvd.nist.gov/vuln/detail/CVE-2023-53433)
 漏洞归属组件：[kernel](https://gitee.com/src-openeuler/kernel)
 漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.4.0,6.6.0
 CVSS V3.x分值：
  BaseScore：5.5 Medium
  Vector：CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  In the Linux kernel, a VLAN protocol parsing vulnerability has been discovered. In affected versions, __vlan_get_protocol() and related functions used pskb_may_pull() instead of skb_header_pointer() for network packet processing. Some callers depended on skb->head being populated with MAC header information, and syzbot caught one of them (skb_mac_gso_segment()). This vulnerability may cause kernel crashes, affecting system confidentiality, integrity, and availability.
