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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2effbe746452c108188f85a6951f2b0b65653840","https://git.kernel.org/stable/c/7a755f6d47b811d3abd93c1642ce5e63894540b8","https://git.kernel.org/stable/c/ec6b083915e8146e147314a5f4f1285d07b57bfc"],"products":[],"source":"nvd","synced_at":"2026-10-28T11:37:51.394563875+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
