CVE-2025-22134

一、漏洞信息
 漏洞编号：[CVE-2025-22134](https://nvd.nist.gov/vuln/detail/CVE-2025-22134)
 漏洞归属组件：[vim](https://gitee.com/src-openeuler/vim)
 漏洞归属的版本：8.2,9.0,9.0.2092,9.1.0764,9.1.1019
 CVSS V3.0分值：
  BaseScore：4.2 Medium
  Vector：CVSS：3.0/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L
 漏洞简述：
  When switching to other buffers using the :all command and visual mode still being active, this may cause a heap-buffer overflow, because Vim does not properly end visual mode and therefore may try to access beyond the end of a line in a buffer. In Patch 9.1.1003 Vim will correctly reset the visual mode before opening other windows and buffers and therefore fix this bug. In addition it does verify that it won t try to access a position if the position is greater than the corresponding buffer line. Impact is medium since the user must have switched on visual mode when executing the :all ex command. The Vim project would like to thank github user gandalf4a for reporting this issue. The issue has been fixed as of Vim patch v9.1.1003
