  "details": "In the Linux kernel, the following vulnerability has been resolved:  fbdev: clear fb_info-\u003emode before deleting a videomode  fb_set_var() can delete a mode from info-\u003emodelist when userspace passes FB_ACTIVATE_INV_MODE through FBIOPUT_VSCREENINFO. The code checks that the mode being deleted is not the current info-\u003evar and that fbcon is not using it, but it does not check fb_info-\u003emode.  fb_info-\u003emode may still point into the modelist entry being deleted. If the entry is freed, later mode sysfs reads through show_mode() can dereference a stale pointer.  Clear fb_info-\u003emode before calling fb_delete_videomode() when it matches the mode being removed.",
