Subject: [PATCH 0/3] Fix bugs in *_set_par() caused by user input
Date: Thu, 4 Aug 2022 20:41:22 +0800 [thread overview]
Message-ID: <20220804124125.3506755-1-zheyuma97@gmail.com> (raw)
In the function *_set_par(), the value of 'screen_size' is
calculated by the user input. If the user provides the improper value,
the value of 'screen_size' may larger than 'info->screen_size', which
may cause a bug in the memset_io().
