Technical Summary
The kak-lsp update to version 21.0.2 fixes a regression breaking compatibility with Kakoune versions older than 2026.05.21, resolves hangs after editing files without trailing newlines, and corrects buffer synchronization corruption when .editorconfig sets insert_final_newline to false. It replaces the default nix language server from nil to nixd and adds a default configuration for Hare using hare-lsp. The vendored crate registry was refreshed, confirming that kak-lsp is not affected by CVE-2026-25541, CVE-2025-3416, and CVE-2025-55159, which affect dependencies but not this package. The update also includes numerous fixes and enhancements from previous versions, such as improved language server support, crash fixes, and better diagnostics handling.
Potential Impact
The update addresses regressions and bugs that could cause compatibility issues, hangs, and buffer synchronization corruption, improving the stability and reliability of kak-lsp. There is no indication that kak-lsp itself is vulnerable to the referenced CVEs in dependencies, so the impact is limited to fixing functional defects rather than remediating direct security vulnerabilities in kak-lsp.
Mitigation Recommendations
A fixed version of kak-lsp is available (version 21.0.2). Users should update to this version to resolve the described issues and benefit from the latest fixes and improvements. Since the package is not affected by the referenced CVEs in dependencies, no additional action is required for those. Patch status is confirmed by the vendor update.
