Errors after allocation call ethosu_job_err_cleanup(), which frees\nthe job but leaks the uninitialized fence.\n\nA scheduler dependency error also lets ethosu_job_run() return before\ndma_fence_init(). Normal cleanup then passes a zeroed refcount to\ndma_fence_put().\n\nRelease done_fence in the common cleanup path and use\ndma_fence_was_initialized() to distinguish initialized fences from raw\nallocations.\n\n[robh: also fix goto]","state":0,"publishedAt":"2026-09-16T10:32:54.518+00:00","modifiedAt":"2026-10-19T08:55:51.093+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_job.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"5a5e9c0228e613f0ef2a58b9782d7c0ea8f1e58b\",\n                            \"lessThan\": \"b3e0f79af1f27339d8d2527c02cc3e8397c2f69f\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"5a5e9c0228e613f0ef2a58b9782d7c0ea8f1e58b\",\n                            \"lessThan\": \"2d2a3adc91950f9a18829dadc7317fb5180a15c5\",\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_job.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\": \"7.2.5\",\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":[],"references":["https://git.kernel.org/stable/c/b3e0f79af1f27339d8d2527c02cc3e8397c2f69f","https://git.kernel.org/stable/c/2d2a3adc91950f9a18829dadc7317fb5180a15c5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-89976","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-89976","identifiers":["CVE-2026-89976"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
