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()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/scsi/qla2xxx/qla_bsg.c"],"versions":[{"version":"01e0e15c8b3b32e006e5cccac10c8b377ac3d803","lessThan":"ef63922d8bdea03de1804af39a6b12212acb1be2","status":"affected","versionType":"git"},{"version":"01e0e15c8b3b32e006e5cccac10c8b377ac3d803","lessThan":"740f3458a4798af54aaf8cf63e797d407e8b6d3b","status":"affected","versionType":"git"},{"version":"01e0e15c8b3b32e006e5cccac10c8b377ac3d803","lessThan":"f75bff451a2fac5aed82f9641df1e9a42c5a899d","status":"affected","versionType":"git"},{"version":"01e0e15c8b3b32e006e5cccac10c8b377ac3d803","lessThan":"4cf38dd9465736141263ebb63375868311a0ec81","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/scsi/qla2xxx/qla_bsg.c"],"versions":[{"version":"4.10","status":"affected"},{"version":"0","lessThan":"4.10","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"6.12.112"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"7.2.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ef63922d8bdea03de1804af39a6b12212acb1be2"},{"url":"https://git.kernel.org/stable/c/740f3458a4798af54aaf8cf63e797d407e8b6d3b"},{"url":"https://git.kernel.org/stable/c/f75bff451a2fac5aed82f9641df1e9a42c5a899d"},{"url":"https://git.kernel.org/stable/c/4cf38dd9465736141263ebb63375868311a0ec81"}],"title":"scsi: qla2xxx: Validate BSG request_len before reading vendor_cmd[]","x_generator":{"engine":"bippy-1.2.0"}}}}
