{"id":"CVE-2026-68316","summary":"accel: ethosu: Fix element size accounting for cmd stream validation","details":"In the Linux kernel, the following vulnerability has been resolved:\n\naccel: ethosu: Fix element size accounting for cmd stream validation\n\nThere are 2 issues with the element size handling in the command stream\nvalidation which result in too small of a size calculated when the\nelement size is 16/32/64 bits.\n\nFor NHWC format, the element size is simply missing from the\ncalculation.\n\nThe bitfield for the element size is different between IFM/IFM2 and\nOFM. IFM and IFM2 encode the precision in parameter bits 2:3, while OFM\nuses bits 1:2.","modified":"2026-08-18T03:31:22.660526084Z","published":"2026-08-10T12:02:51.141Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68316.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/18a551482a4a326790698b273e76d7575a51a57d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b4ae748f8e6cb65bb86e5a281bbb5b5e5f106527"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68316.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68316"},{"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":"5a5e9c0228e613f0ef2a58b9782d7c0ea8f1e58b"},{"fixed":"b4ae748f8e6cb65bb86e5a281bbb5b5e5f106527"},{"fixed":"18a551482a4a326790698b273e76d7575a51a57d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68316.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68316.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"}]}
