{"apiVersion":"1.0","identifier":"CVE-2026-74444","description":"In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: validate DRAW_PRIMITIVES header size before division vmw_cmd_draw() computes maxnum = (header->size - sizeof(cmd->body)) / sizeof(*decl); where header->size is u32 and is taken straight from the user-supplied command stream. When header->size is less than sizeof(cmd->body) the unsigned subtraction wraps to nearly 4 GiB, producing a huge maxnum. Any user-controlled cmd->body.numVertexDecls then passes the bound and the loop dereferences decl[i] far past the end of the kernel command bounce buffer, producing an out-of-bounds read of kernel memory. Reject undersized headers up front.","publishedAt":"2026-08-15T13:17:48","lastModifiedAt":"2026-08-19T17:21:01","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74444","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-2026-74444","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74444","en":"https://www.redsauce.net/en/cves/CVE-2026-74444","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74444","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74444","de":"https://www.redsauce.net/de/cves/CVE-2026-74444","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74444","el":"https://www.redsauce.net/el/cves/CVE-2026-74444"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74444"}}
