On U65 the same field holds the rounding mode, and the\ncommand stream parser has read it as a storage mode since the driver was\nadded.\n\nThat went unnoticed while unknown values fell through the switch, but\nnow that they are rejected, every U65 command stream that asks for\nnatural rounding (2) fails CMDSTREAM_BO_CREATE with -EINVAL. Mesa emits\nit for average pooling, concatenation, split, unpack, strided slice, LUT\nand argmax, which is 72 failures of the Teflon test suite on an i.MX93.\nTruncating rounding (1) is misread as well: it picks the two-tile\naddress path and computes a bogus feature map size from tile bases the\ncommand stream never set.\n\nRead the field as a storage mode only on the hardware where it is one.","state":0,"publishedAt":"2026-09-25T10:36:18.47+00:00","modifiedAt":"2026-10-19T09:14:36.709+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/accel/ethosu/ethosu_gem.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"5a5e9c0228e613f0ef2a58b9782d7c0ea8f1e58b\",\n                            \"lessThan\": \"6b08adbda8ea797849e3654ce12cb3856ce6051a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"5a5e9c0228e613f0ef2a58b9782d7c0ea8f1e58b\",\n                            \"lessThan\": \"db9deec5a345abc538d081fb221dc0b00a9695bd\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/accel/ethosu/ethosu_gem.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.19\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.7\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/6b08adbda8ea797849e3654ce12cb3856ce6051a","https://git.kernel.org/stable/c/db9deec5a345abc538d081fb221dc0b00a9695bd"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98143","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98143","identifiers":["CVE-2026-98143"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
