{"apiVersion":"1.0","identifier":"CVE-2026-80579","description":"In the Linux kernel, the following vulnerability has been resolved: fbdev: clear fb_info->mode before deleting a videomode fb_set_var() can delete a mode from info->modelist when userspace passes FB_ACTIVATE_INV_MODE through FBIOPUT_VSCREENINFO. The code checks that the mode being deleted is not the current info->var and that fbcon is not using it, but it does not check fb_info->mode. fb_info->mode 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->mode before calling fb_delete_videomode() when it matches the mode being removed.","publishedAt":"2026-08-26T15:17:14","lastModifiedAt":"2026-08-27T06:17:44","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80579","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00112,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80579","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80579","en":"https://www.redsauce.net/en/cves/CVE-2026-80579","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80579","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80579","de":"https://www.redsauce.net/de/cves/CVE-2026-80579","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80579","el":"https://www.redsauce.net/el/cves/CVE-2026-80579"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80579"}}
