How to fix?

Upgrade Debian:unstable vim to version 2:9.2.0858-1 or higher.

NVD Description

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

Vim is an open source, command line text editor. From 9.2.0469 until 9.2.0843, popup_mark_opacity_zindex() in src/popupwin.c can use a negative w_winrow for a text-property-anchored popup with clipwindow and opacity, indexing before the screen array instead of accounting for w_popup_topoff and causing an out-of-bounds read and conditional write. This issue is fixed in version 9.2.0843.
