Since the structure is stored in shared\nAMDXDNA_BO_SHARE memory, userspace can modify command_count concurrently.\nIf command_count is changed to zero, the bounds check generated from\n__counted_by may fail and trigger a kernel panic.\n\nRemove __counted_by to avoid relying on the userspace-controlled\ncommand_count for the flexible array bounds check.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98146","source_modified_at":"2026-10-19T09:14:39.513Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"aac243092b707bb3018e951d470cc1a9bcbaba6c","lessThan":"93fa3e925b15b0ded0a549fe7f12bfbb1c4e171a","status":"affected","versionType":"git"},{"version":"aac243092b707bb3018e951d470cc1a9bcbaba6c","lessThan":"52f3e086760a9a3e02a46a10b57caffd73b1c204","status":"affected","versionType":"git"},{"version":"aac243092b707bb3018e951d470cc1a9bcbaba6c","lessThan":"b3709d354545e70388177500761f92d906c4dfd6","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98146","source_modified_at":"2026-10-19T09:14:39.513Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.14","status":"affected"},{"version":"0","lessThan":"6.14","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98146","source_modified_at":"2026-10-19T09:14:39.513Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"93fa3e925b15b0ded0a549fe7f12bfbb1c4e171a","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98146","source_modified_at":"2026-10-19T09:14:39.513Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"52f3e086760a9a3e02a46a10b57caffd73b1c204","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.0009,"percentile":0.00409,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:36:20.303Z","modified_at":"2026-10-19T09:14:39.513Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98146","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:14:39.513Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98146","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/93fa3e925b15b0ded0a549fe7f12bfbb1c4e171a"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/52f3e086760a9a3e02a46a10b57caffd73b1c204"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/b3709d354545e70388177500761f92d906c4dfd6"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:14:39.513Z","content_hash":"92f898ec1ef78580676d07c6ef27224a3eb1ab974e045f05103617db0ee3fcdf"}}
