  "description": "In the Linux kernel, the following vulnerability has been resolved:  video: fbdev: arkfb: Check the size of screen before memset_io()  In the function arkfb_set_par(), the value of \u0027screen_size\u0027 is calculated by the user input. If the user provides the improper value, the value of \u0027screen_size\u0027 may larger than \u0027info-\u003Escreen_size\u0027, which may cause the following bug:  [  659.399066] BUG: unable to handle page fault for address: ffffc90003000000 [  659.399077] #PF: supervisor write access in kernel mode [  659.399079] #PF: error_code(0x0002) - not-present page [  659.399094] RIP: 0010:memset_orig\u002B0x33/0xb0 [  659.399116] Call Trace: [  659.399122]  arkfb_set_par\u002B0x143f/0x24c0 [  659.399130]  fb_set_var\u002B0x604/0xeb0 [  659.399161]  do_fb_ioctl\u002B0x234/0x670 [  659.399189]  fb_ioctl\u002B0xdd/0x130  Fix the this by checking the value of \u0027screen_size\u0027 before memset_io().",
