{"apiVersion":"1.0","identifier":"CVE-2026-74617","description":"In the Linux kernel, the following vulnerability has been resolved: dibs: initialise dibs->lock in dibs_dev_alloc() dibs->lock is initialised by dibs_dev_add(), but a dibs device can already take interrupts before that call: ism_probe() runs ism_dev_init(), and hence request_irq(), before it calls dibs_dev_add(). No client can have registered a dmb at that point, so no dmb interrupt can occur, but a GID event interrupt can, and ism_handle_irq() takes dibs->lock unconditionally on entry, before it inspects anything else. Initialise the lock in dibs_dev_alloc() instead, so that it is valid as soon as a driver can publish the device to its interrupt handler.","publishedAt":"2026-08-22T16:16:34","lastModifiedAt":"2026-08-25T06:18:40","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74617","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00442,"riskScore":1.02,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74617","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74617","en":"https://www.redsauce.net/en/cves/CVE-2026-74617","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74617","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74617","de":"https://www.redsauce.net/de/cves/CVE-2026-74617","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74617","el":"https://www.redsauce.net/el/cves/CVE-2026-74617"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74617"}}
