  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nfbdev: clear fb_info-\u003emode before deleting a videomode\n\nfb_set_var() can delete a mode from info-\u003emodelist when userspace\npasses FB_ACTIVATE_INV_MODE through FBIOPUT_VSCREENINFO. The code\nchecks that the mode being deleted is not the current info-\u003evar and\nthat fbcon is not using it, but it does not check fb_info-\u003emode.\n\nfb_info-\u003emode may still point into the modelist entry being deleted.\nIf the entry is freed, later mode sysfs reads through show_mode() can\ndereference a stale pointer.\n\nClear fb_info-\u003emode before calling fb_delete_videomode() when it\nmatches the mode being removed.",
