  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Validate BSG request_len before reading vendor_cmd[]\n\nThe FC BSG transport allocates job-\u003erequest via memdup_user() using the\nexact user-supplied request_len. For FC_BSG_HST_VENDOR,\nfc_bsg_host_dispatch() only guarantees request_len covers msgcode and\nvendor_id; it does not account for the vendor_cmd[] flexible array.\n\nqla2xxx then reads the command selector vendor_cmd[0] and, in several\nsub-handlers, vendor_cmd[1]/[2] or structures overlaid on the vendor\ncommand area without verifying request_len. A caller holding\nCAP_SYS_RAWIO can submit a short request whose vendor_id matches the\nhost, triggering out-of-bounds heap reads (KASAN-detectable, and able to\nmis-select a command or panic).\n\nAdd a central guard in qla2x00_process_vendor_specific() so the selector\nis always in bounds, restrict the early vendor_cmd[0] read in\nqla24xx_bsg_request() to sufficiently long vendor messages, and add\nrequest_len checks to the sub-handlers that read further:\nqla24xx_proc_fcp_prio_cfg_cmd(), qla2x00_process_loopback(),\nqla84xx_reset(), qla84xx_updatefw(), qla2x00_read_optrom(),\nqla2x00_update_optrom(), qlafx00_mgmt_cmd() and\nqla28xx_validate_flash_image().",
