The count is\nthen walked at a fixed 32-byte stride in two places with no bound: the\nlog read here, and the INQUIRY VPD page B9h emitter, which writes one\ndescriptor per range into the fixed 2048-byte ata_scsi_rbuf. A device\nreporting a count larger than its own log overflows the read buffer (up\nto 7704 bytes past a 512-byte slab), and a count above 62 overflows the\nresponse buffer on the emit side.\n\nBound the count once, on probe, against both the log the device returned\nand the number of descriptors the VPD B9h response buffer can hold\n(ATA_DEV_MAX_CPR, derived from the rbuf size). Reject an out-of-range\ncount with a warning; this keeps the emitter in bounds with no separate\nchange there."
