{"apiVersion":"1.0","identifier":"CVE-2026-74313","description":"In the Linux kernel, the following vulnerability has been resolved: vduse: hold vduse_lock across IDR lookup in open path vduse_dev_open() looks up struct vduse_dev through the IDR and then acquires dev->lock only after vduse_lock has been dropped. This leaves a window where a concurrent VDUSE_DESTROY_DEV can remove the same object from the IDR and free it before the open path locks the device, leading to a use-after-free. Close this race by keeping vduse_lock held until dev->lock has been acquired in the open path, matching the lock ordering already used by the destroy path.","publishedAt":"2026-08-15T06:22:31","lastModifiedAt":"2026-08-17T06:19:25","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74313","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00126,"riskScore":0.89,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74313","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74313","en":"https://www.redsauce.net/en/cves/CVE-2026-74313","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74313","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74313","de":"https://www.redsauce.net/de/cves/CVE-2026-74313","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74313","el":"https://www.redsauce.net/el/cves/CVE-2026-74313"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74313"}}
