  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Bound rsp_info_len to avoid OOB sense-data read\n\nIn qla2x00_status_entry(), the FWI2 status path advances sense_data and\nshrinks par_sense_len by rsp_info_len:\n\n\tif (IS_FWI2_CAPABLE(ha)) {\n\t\tsense_data += rsp_info_len;\n\t\tpar_sense_len -= rsp_info_len;\n\t}\n\nrsp_info_len is a 32-bit value taken directly from the target's FCP\nresponse (sf.rsp_data_len), while par_sense_len is the IOCB data area\nsize (28 bytes for 24xx, 60 bytes for 29xx). A hostile or buggy target\nreporting an rsp_info_len larger than par_sense_len makes the unsigned\nsubtraction underflow to a huge value and advances sense_data out of\nbounds.\n\nThe underflowed par_sense_len then defeats the cap in\nqla2x00_handle_sense():\n\n\tif (sense_len \u003e par_sense_len)\n\t\tsense_len = par_sense_len;\n\tmemcpy(cp-\u003esense_buffer, sense_data, sense_len);\n\nso the memcpy reads up to SCSI_SENSE_BUFFERSIZE bytes from the\nout-of-bounds sense_data pointer, leaking adjacent response-ring/heap\nmemory into the command's sense buffer.\n\nClamp rsp_info_len to par_sense_len before the subtraction so\npar_sense_len can never underflow and sense_data stays within the IOCB\ndata area. The fix sits before the comp_status switch, covering both\nqla2x00_handle_sense() call sites.",
