{"cve":"CVE-2026-89844","nvd":{"published":"2026-09-16T11:16:51.567","modified":"2026-10-19T09:18:28.360","status":"Received","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Hold vport_slock for host map update in report ID acquisition\n\nqla24xx_report_id_acquisition() format-1 handling drops vport_slock after\ntaking the vport reference and then calls qla_update_host_map() without\nthe lock. That reaches qla_update_vp_map(), which mutates the ha->host_map\nbtree via btree_insert32()/btree_update32()/btree_remove32() and is\ndocumented to require vport_slock to be held by the caller. Running it\nunlocked can race concurrent host_map updates and corrupt the btree.\n\nThe format-2 path in the same function already wraps its host_map update\n(SET_AL_PA) in vport_slock; the format-1 path is the lone outlier.\n\nHold vport_slock across the format-1 qla_update_host_map() call to honor\nthe documented locking contract. The vref_count taken in the loop keeps\nthe vport valid, so this only adds the missing host_map serialization.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":[],"references":["https://git.kernel.org/stable/c/6ed66e2a67bbd22877008ff9aa64bd574a7fc011","https://git.kernel.org/stable/c/776e4e8cbcf155302f430ce9793d1502e3c113a0","https://git.kernel.org/stable/c/7944039ba9cb5c3a935d17c91004e3b8649ff58e","https://git.kernel.org/stable/c/7d0b3f745efb24c0aac5e06b49b3420bc65d23b9","https://git.kernel.org/stable/c/e8f1b0cb9782338c6341ceed816e9c1243743cdd"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-89844","score":0.00338,"percentile":0.26939,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
