DescriptionCVE.org

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.

AnalysisAI

Out-of-bounds read and conditional write in Vim 9.2.0469 through 9.2.0842 can be triggered when a text-property-anchored popup window is configured with both clipwindow and opacity settings active. The defect in popup_mark_opacity_zindex() (src/popupwin.c) fails to account for w_popup_topoff when w_winrow is negative, causing the function to index before the start of the screen array - a classic buffer underwrite (CWE-124). …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the affected Vim version (9.2.0469-9.2.0842) is running locally on the target system, and that the user opens or executes a Vim session (via a crafted file, script, or plugin) that simultaneously activates a text-property-anchored popup window configured with both the 'clipwindow' and 'opacity' options. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 4.6 with vector AV:L/AC:L/AT:N/PR:N/UI:A accurately reflects the constrained threat model: exploitation requires local system access and active user interaction (the user must open or execute a Vim session triggering the specific popup configuration). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A local user or a malicious file opened in Vim triggers a scenario where a text-property-anchored popup window is rendered with both the clipwindow and opacity options active, causing the popup's computed top row to become negative. This induces `popup_mark_opacity_zindex()` to index before the screen array boundary, resulting in a memory read from an out-of-bounds location and a potential conditional write, which could crash the Vim process or corrupt adjacent memory. …
Remediation Upgrade Vim to version 9.2.0843 or later, which contains the upstream fix for this issue per the vendor security advisory at https://github.com/vim/vim/security/advisories/GHSA-pmvp-6rcj-98p4. … Detailed patch versions, workarounds, and compensating controls in full report.
