{"apiVersion":"1.0","identifier":"CVE-2026-74306","description":"In the Linux kernel, the following vulnerability has been resolved: vfio/qat: fix f_pos race in qat_vf_resume_write() qat_vf_resume_write() checks filp->f_pos before taking migf->lock, but copies into the migration-state buffer after taking the lock and re-reading the shared file position. Two concurrent writers could therefore pass the bounds check with the old offset, then have the second writer copy after the first advanced f_pos, writing past the end of the migration-state buffer. Take migf->lock before doing the boundary checks.","publishedAt":"2026-08-15T06:22:30","lastModifiedAt":"2026-08-17T06:19:24","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74306","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00129,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74306","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74306","en":"https://www.redsauce.net/en/cves/CVE-2026-74306","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74306","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74306","de":"https://www.redsauce.net/de/cves/CVE-2026-74306","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74306","el":"https://www.redsauce.net/el/cves/CVE-2026-74306"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74306"}}
