CVE-2022-50102

CVE-2022-50102 affects the Linux kernel’s fbdev arkfb driver. A user-controlled ioctl can cause a divide-by-zero in ark_set_pixclock, e.g. with hdiv=1, pixclock=1, hmul=2, producing (1*1)/2 = 0 and leading to division by zero later in arkfb.c when computing 1000000000 / pixclock. The vulnerabilit...
