+Subject: [PATCH 2/3] Fix heap-buffer-overflow in raw file loading
+
+When `jv_string_append_buf` overflows the string length limit,
+it returns an invalid `jv`; `jv_load_file` then re-entered it
+on the invalid value and overran the heap. Break out of the loop
+once the value is invalid.
+
+Fixes CVE-2026-49839.
