I have a problem with my MySQL database. RAM usage is too high, CPU too.

Does it come from my configuration ?

Here's my configuration :

I must be more precise in one point. RAM is growing even if running slow queries, sounds like a mem leak But I don't know, I prefer to ask to a confirmed DBA

@Salim With available information, suggestions to consider

REMOVE from your configuration log_error  to allow default error log file name
innodb_print_all_deadlocks=1  # from OFF to enable identification and pursue correcting.
key_cache_block_size=16384  # from 1024 to reduce overhead managing key_buffer_size
key_cache_division_limit=50  # from 100 percent for Hot and Warm cache
key_cache_age_threshold=7200  # from 300 seconds before AGE-OUT of indx in ram  These three variables, after implementation will reduce key_reads Rate Per Second of 1,910.

Observations, When your log_error is stderr, there is no hope of determining what happened several hours ago to your server. com_rollback counted 18 events in 3,131 seconds and you have NO record of the cause with current configuration. innodb_print_all_deadlocks may help you here. com_stmt_prepare count is usually paired with com_stmt_close. In your STATUS, reporting, com_stmt_close indicates 46,545 prepares did not have CLOSE, leaving resources in use. Reducing ram available over your 3,131 seconds of uptime.
