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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/2effbe746452c108188f85a6951f2b0b65653840","tags":[]},{"url":"https://git.kernel.org/stable/c/7a755f6d47b811d3abd93c1642ce5e63894540b8","tags":[]},{"url":"https://git.kernel.org/stable/c/ec6b083915e8146e147314a5f4f1285d07b57bfc","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
