{"apiVersion":"1.0","identifier":"CVE-2026-80721","description":"In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: ensure no dangling hcon references in iso_conn After iso_conn_del(), ISO sockets should not dereference the hcon any more. Currently, clearing iso_conn::hcon relies on iso_conn_del() releasing the last reference to the iso_conn. Simplify this by explicitly clearing conn->hcon in iso_conn_del(), to avoid more complex reasoning on races about who holds the last reference.","publishedAt":"2026-08-28T08:16:57","lastModifiedAt":"2026-08-28T08:16:57","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80721","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00154,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80721","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80721","en":"https://www.redsauce.net/en/cves/CVE-2026-80721","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80721","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80721","de":"https://www.redsauce.net/de/cves/CVE-2026-80721","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80721","el":"https://www.redsauce.net/el/cves/CVE-2026-80721"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80721"}}
