{"cve":"CVE-2026-97535","nvd":{"published":"2026-09-25T11:17:03.757","modified":"2026-10-21T13:21:12.860","status":"Received","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Bound VP index against VP_CTRL IOCB bitmap size\n\nThe VP control IOCB selects its target virtual port by setting one bit\nin vp_idx_map, a fixed 16-byte (128-bit) array in both\nvp_ctrl_entry_24xx and vp_ctrl_entry_24xx_ext. qla25xx_ctrlvp_iocb()\ncomputes map = (vp_index - 1) / 8 and writes vce->vp_idx_map[map]\nwithout checking that map stays within the array.\n\nmax_npiv_vports is taken from firmware and only sanitized to a\nMIN_MULTI_ID_FABRIC-aligned boundary, so it can legitimately be 191 or\n255, and qla24xx_control_vp() only rejects vp_index >= max_npiv_vports.\nA vp_index above 128 therefore yields map >= 16 and an out-of-bounds\nwrite of up to 16 bytes past vp_idx_map, corrupting the trailing IOCB\nfields (or the adjacent request-ring slot on the 64-byte layout).\n\nReject a vp_index that cannot be represented in the IOCB bitmap in\nqla24xx_control_vp(), and add a defensive ARRAY_SIZE() guard in\nqla25xx_ctrlvp_iocb() before the write. Adapters that report the usual\n63 or 127 NPIV vports are unaffected.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/13354ad251ab009102597a791bc7c4d2265229e1","https://git.kernel.org/stable/c/48a44e19746eaa70320a3c2571dcb345192fca72","https://git.kernel.org/stable/c/674d783f2e80d0d7c1c86bf36dc0a09033e704de","https://git.kernel.org/stable/c/878613ecb5a36db26859c4fd83daf9283a334fa2","https://git.kernel.org/stable/c/c80a0362a0fe548c15a0324b1f61c04b62bb2174"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-97535","score":0.00206,"percentile":0.10565,"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).
