Also set dmc_fw_size only\nafter the payload allocation succeeds.\n\n(cherry picked from commit efde6601a1f1daedfe3dcc2816c934ddb44e3eef)","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99118","source_modified_at":"2026-10-28T10:34:34.627Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"eb805623d8b161342ed9c9caf366f0a295041a6d","lessThan":"dfcfe2874e7c16e8460dc86ac1eeb54ea0e7f8aa","status":"affected","versionType":"git"},{"version":"eb805623d8b161342ed9c9caf366f0a295041a6d","lessThan":"05f7a2f712f8b287a98ee61a7c2c6b72dad2fc6d","status":"affected","versionType":"git"},{"version":"eb805623d8b161342ed9c9caf366f0a295041a6d","lessThan":"8bb1858db453cd4250e3b633f5d2d09206024ca6","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99118","source_modified_at":"2026-10-28T10:34:34.627Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"4.2","status":"affected"},{"version":"0","lessThan":"4.2","status":"unaffected","versionType":"semver"},{"version":"6.18.59","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.13","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-2026-99118","source_modified_at":"2026-10-28T10:34:34.627Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"05f7a2f712f8b287a98ee61a7c2c6b72dad2fc6d","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99118","source_modified_at":"2026-10-28T10:34:34.627Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"8bb1858db453cd4250e3b633f5d2d09206024ca6","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T10:34:34.627Z","modified_at":"2026-10-28T10:34:34.627Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99118","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T10:34:34.627Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/dfcfe2874e7c16e8460dc86ac1eeb54ea0e7f8aa"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/05f7a2f712f8b287a98ee61a7c2c6b72dad2fc6d"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/8bb1858db453cd4250e3b633f5d2d09206024ca6"}],"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":"2026-10-28T10:34:34.627Z","content_hash":"7ddd8895461262c6c6e24895d265e875cc4b874dc86489a6b70c1fd819477911"}}
