{"apiVersion":"1.0","identifier":"CVE-2026-74538","description":"In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: lock sk in iso_connect_ind Accessing iso_pi(sk)->conn requires lock_sock, which is not taken in the -ev3- part of iso_connect_ind. It may also be NULL if socket has transitioned away from the LISTEN/CONNECT states before locking. Fix by adding lock/release. Recheck hcon is valid after lock acquire where needed.","publishedAt":"2026-08-15T13:17:59","lastModifiedAt":"2026-08-17T06:19:50","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74538","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00239,"riskScore":0.9,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74538","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74538","en":"https://www.redsauce.net/en/cves/CVE-2026-74538","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74538","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74538","de":"https://www.redsauce.net/de/cves/CVE-2026-74538","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74538","el":"https://www.redsauce.net/el/cves/CVE-2026-74538"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74538"}}
