`_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.

Exploitation probability (EPSS)

FIRST hasn't scored this CVE yet (usual for very recent or rejected CVEs).

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

CWE-125 con AV:L, PR:N y UI:A: la lectura fuera de límites exige interacción; el texto no describe ejecución de comandos, así que T1059 de la pista no se sustenta.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
