Author: Ilia Alshanetsky (iliaal) Date: 2026-10-01T10:08:41-04:00 Commit: https://github.com/php/php-src/commit/a1e5424af2154432b03a63c7f95b390560ae1489 Raw diff: https://github.com/php/php-src/commit/a1e5424af2154432b03a63c7f95b390560ae1489.diff ext/mysqlnd: Fix VIO plugin area getter mysqlnd_plugin_get_plugin_vio_data() expanded to get_pfc_area(), which offsets by sizeof(MYSQLND_PFC) instead of sizeof(MYSQLND_VIO). The returned slot is two pointers too far, so a plugin reads and writes another plugin's slot or, for the highest plugin ids, the MYSQLND_VIO_DATA allocated right after the area. Call get_vio_area() instead.
