{"id":"CVE-2026-74417","summary":"drm/radeon: fix integer overflow in radeon_align_pitch()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/radeon: fix integer overflow in radeon_align_pitch()\n\nradeon_align_pitch() has the same kind of overflow issue as the old\namdgpu helper: both the alignment round-up add and the final\n'aligned * cpp' calculation can overflow signed int.\n\nIf that wraps, radeon_mode_dumb_create() can end up returning an\ninvalid pitch or creating a zero-sized dumb buffer.\n\nFix this by using check_add_overflow() for the alignment round-up and\ncheck_mul_overflow() for the final pitch calculation, returning 0 on\noverflow. Also reject zero pitch and size in\nradeon_mode_dumb_create().\n\nFound via AST-based call-graph analysis using sqry.","modified":"2026-08-18T03:56:57.653559803Z","published":"2026-08-15T05:59:22.731Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74417.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/415bb9893e249e46aa5159f7363a11512cf06fa9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b7b44937c548c2c987fcdd129f8896741004bed6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ce3b24eb3ee8f82de851535f516bf21f83e82259"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d9dfa176899d488e48bb7342d2c43ddd36e66318"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dfc7b5b5599472277e71e5bd2712740651c7c5be"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74417.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74417"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ff72145badb834e8051719ea66e024784d000cb4"},{"fixed":"b7b44937c548c2c987fcdd129f8896741004bed6"},{"fixed":"415bb9893e249e46aa5159f7363a11512cf06fa9"},{"fixed":"d9dfa176899d488e48bb7342d2c43ddd36e66318"},{"fixed":"dfc7b5b5599472277e71e5bd2712740651c7c5be"},{"fixed":"ce3b24eb3ee8f82de851535f516bf21f83e82259"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74417.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.39"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74417.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
