{"id":"CVE-2026-97531","summary":"scsi: qla2xxx: Skip vport under deletion in report ID acquisition","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Skip vport under deletion in report ID acquisition\n\nqla24xx_report_id_acquisition() format-1 handling walks ha-\u003evp_list under\nvport_slock, takes a vref_count on the matching vport and calls\nqla_update_host_map() to register its port id.\n\nA vport teardown via qla24xx_vport_delete() sets VPORT_DELETE, then\nqla24xx_disable_vp() removes the vport from the host_map btree and zeroes\nvha-\u003ed_id (RESET_AL_PA). The vport is only unlinked from vp_list later,\nin qla24xx_deallocate_vp_id(), which clears vp_map[idx] (RESET_VP_IDX)\nbut does not touch host_map. In the window in between, report ID\nacquisition can still find the vport on vp_list and call\nqla_update_host_map(); with d_id already zeroed it takes the\nbtree_insert32() path and re-inserts the dying vport into host_map.\nNothing cleans that entry afterwards, so once scsi_host_put() frees the\nvha a later host_map lookup dereferences freed memory.\n\nSkip a vport that has VPORT_DELETE set before taking the reference, so it\nis neither re-registered nor scheduled for DPC re-registration. This\nmirrors the existing guard in qla2x00_alert_all_vps().","modified":"2026-09-26T03:48:29.009427343Z","published":"2026-09-25T10:21:31.968Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97531.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/23582731afa35031c94fadb71a4f3b4afd094649"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a83979d92782f83c90888ebe19bdc9420521940"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d61e8de98c5a52978fb1edd95fe4dde3131b280e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97531.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97531"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"41dc529a4602ac737020f423f84686a81de38e6d"},{"fixed":"d61e8de98c5a52978fb1edd95fe4dde3131b280e"},{"fixed":"7a83979d92782f83c90888ebe19bdc9420521940"},{"fixed":"23582731afa35031c94fadb71a4f3b4afd094649"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97531.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.11.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97531.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
