CVE-2021-47383

CVE-2021-47383 : In the Linux kernel, the tty imageblit out-of-bounds access is caused when an ioctl FBIOPUT_VSCREENINFO with only xres, yres, and bits_per_pixel is sent and the struct matches the previous ioctl. This leaves fb_var_screeninfo incomplete, causing updatescrollmode() to compute a wr...
