Geert Uytterhoeven f9a40df232 fbdev: controlfb: Add missing modes to fix out of bounds access ... [ Upstream commit ac831a379d ] Dan's static analysis says: drivers/video/fbdev/controlfb.c:560 control_setup() error: buffer overflow 'control_mac_modes' 20 <= 21 Indeed, control_mac_modes[] has only 20 elements, while VMODE_MAX is 22, which may lead to an out of bounds read when parsing vmode commandline options. The bug was introduced in v2.4.5.6, when 2 new modes were added to macmodes.h, but control_mac_modes[] wasn't updated: https://kernel.opensuse.org/cgit/kernel/diff/include/video/macmodes.h?h=v2.5.2&id=29f279c764808560eaceb88fef36cbc35c529aad Augment control_mac_modes[] with the two new video modes to fix this.
