How to fix?

Upgrade SLES:15.6 gvim to version 9.1.1101-150500.20.21.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream gvim package and not the gvim package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

Vim is an open source command line text editor. When performing a search and displaying the search-count message is disabled (:set shm+=S), the search pattern is displayed at the bottom of the screen in a buffer (msgbuf). When right-left mode (:set rl) is enabled, the search pattern is reversed. This happens by allocating a new buffer. If the search pattern contains some ASCII NUL characters, the buffer allocated will be smaller than the original allocated buffer (because for allocating the reversed buffer, the strlen() function is called, which only counts until it notices an ASCII NUL byte ) and thus the original length indicator is wrong. This causes an overflow when accessing characters inside the msgbuf by the previously (now wrong) length of the msgbuf. The issue has been fixed as of Vim patch v9.1.0689.
