{"apiVersion":"1.0","identifier":"CVE-2026-74703","description":"In the Linux kernel, the following vulnerability has been resolved: vhost-scsi: Validate T10 PI scatterlist counts When T10 PI is negotiated, vhost-scsi splits protection bytes from the data iterator before mapping the request scatterlists. A malformed request can claim protection bytes that cover or exceed the full payload length. The former leaves no data bytes to map, while the latter underflows exp_data_len before advancing the iterator. Both cases can let a zero data SGL count reach sg_alloc_table_chained(), which triggers BUG_ON(!nents). Reject protection lengths that cover or exceed the payload before subtracting prot_bytes and advancing the iterator. Also propagate negative errors from the protection SGL calculation before calling the allocator, matching the data SGL path.","publishedAt":"2026-08-22T16:16:44","lastModifiedAt":"2026-08-25T06:18:54","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74703","cvssScore":7.1,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","epssProbability":0.00137,"riskScore":0.72,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74703","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74703","en":"https://www.redsauce.net/en/cves/CVE-2026-74703","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74703","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74703","de":"https://www.redsauce.net/de/cves/CVE-2026-74703","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74703","el":"https://www.redsauce.net/el/cves/CVE-2026-74703"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74703"}}
