{"apiVersion":"1.0","identifier":"CVE-2026-74417","description":"In the Linux kernel, the following vulnerability has been resolved: drm/radeon: fix integer overflow in radeon_align_pitch() radeon_align_pitch() has the same kind of overflow issue as the old amdgpu helper: both the alignment round-up add and the final -aligned * cpp- calculation can overflow signed int. If that wraps, radeon_mode_dumb_create() can end up returning an invalid pitch or creating a zero-sized dumb buffer. Fix this by using check_add_overflow() for the alignment round-up and check_mul_overflow() for the final pitch calculation, returning 0 on overflow. Also reject zero pitch and size in radeon_mode_dumb_create(). Found via AST-based call-graph analysis using sqry.","publishedAt":"2026-08-15T06:22:43","lastModifiedAt":"2026-08-17T06:19:37","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74417","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.0012,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74417","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74417","en":"https://www.redsauce.net/en/cves/CVE-2026-74417","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74417","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74417","de":"https://www.redsauce.net/de/cves/CVE-2026-74417","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74417","el":"https://www.redsauce.net/el/cves/CVE-2026-74417"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74417"}}
