When an Advanced RPMB command\nreturns an EHS, ufshcd_advanced_rpmb_req_handler() copies it right after\nthe 40-byte header and writes 8 bytes past the end of the buffer.\n\nLet each BSG transport pass its reply buffer size to bsg_setup_queue()\nand have ufs_bsg request sizeof(struct ufs_rpmb_reply), so the full\nreply reaches user space. Other transports keep SCSI_SENSE_BUFFERSIZE.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99157","source_modified_at":"2026-10-28T10:35:11.192Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"6ff265fc5ef660499e0edc4641647e99eed3f519","lessThan":"2effbe746452c108188f85a6951f2b0b65653840","status":"affected","versionType":"git"},{"version":"6ff265fc5ef660499e0edc4641647e99eed3f519","lessThan":"7a755f6d47b811d3abd93c1642ce5e63894540b8","status":"affected","versionType":"git"},{"version":"6ff265fc5ef660499e0edc4641647e99eed3f519","lessThan":"ec6b083915e8146e147314a5f4f1285d07b57bfc","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99157","source_modified_at":"2026-10-28T10:35:11.192Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.3","status":"affected"},{"version":"0","lessThan":"6.3","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-2026-99157","source_modified_at":"2026-10-28T10:35:11.192Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"2effbe746452c108188f85a6951f2b0b65653840","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99157","source_modified_at":"2026-10-28T10:35:11.192Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"7a755f6d47b811d3abd93c1642ce5e63894540b8","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":"2026-10-28T10:35:11.192Z","modified_at":"2026-10-28T10:35:11.192Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99157","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T10:35:11.192Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/2effbe746452c108188f85a6951f2b0b65653840"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/7a755f6d47b811d3abd93c1642ce5e63894540b8"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ec6b083915e8146e147314a5f4f1285d07b57bfc"}],"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":"2026-10-28T10:35:11.192Z","content_hash":"7c8134d316a49a41bce39d3d8b46bbe9d7ee1b572b2cb8ee58a6f6139a4311c8"}}
