Summary
`_gx_multi_line_text_view_display_info_get()` reads one byte past the end of the application's text buffer when the string it is given ends with a carriage return (`\r`). The over-read can also cause callers to advance their index past the end of the string, producing a second over-read in `_gx_multi_line_text_view_string_total_rows_compute()` and a row of text that is not in the source.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of eclipse-threadx/guix published their own advisory on GitHub. Reviewed sources take precedence over it.
