  "description": "In the Linux kernel, the following vulnerability has been resolved:  video: fbdev: i740fb: Check the argument of i740_calc_vclk()  Since the user can control the arguments of the ioctl() from the user space, under special arguments that may result in a divide-by-zero bug.  If the user provides an improper \u0027pixclock\u0027 value that makes the argumet of i740_calc_vclk() less than \u0027I740_RFREQ_FIX\u0027, it will cause a divide-by-zero bug in:     drivers/video/fbdev/i740fb.c:353 p_best = min(15, ilog2(I740_MAX_VCO_FREQ / (freq / I740_RFREQ_FIX)));  The following log can reveal it:  divide error: 0000 [#1] PREEMPT SMP KASAN PTI RIP: 0010:i740_calc_vclk drivers/video/fbdev/i740fb.c:353 [inline] RIP: 0010:i740fb_decode_var drivers/video/fbdev/i740fb.c:646 [inline] RIP: 0010:i740fb_set_par\u002B0x163f/0x3b70 drivers/video/fbdev/i740fb.c:742 Call Trace:  fb_set_var\u002B0x604/0xeb0 drivers/video/fbdev/core/fbmem.c:1034  do_fb_ioctl\u002B0x234/0x670 drivers/video/fbdev/core/fbmem.c:1110  fb_ioctl\u002B0xdd/0x130 drivers/video/fbdev/core/fbmem.c:1189  Fix this by checking the argument of i740_calc_vclk() first.",
