The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream vim.src package and not the vim.src package as distributed by Centos.
Vim is an open source, command line text editor. Prior to 9.1.2148, a stack buffer overflow vulnerability exists in Vim's NetBeans integration when processing the specialKeys command, affecting Vim builds that enable and use the NetBeans feature. The Stack buffer overflow exists in special_keys() (in src/netbeans.c). The while (*tok) loop writes two bytes per iteration into a 64-byte stack buffer (keybuf) with no bounds check. A malicious NetBeans server can overflow keybuf with a single specialKeys command. The issue has been fixed as of Vim patch v9.1.2148.
