Removal can set that bit immediately afterwards and free\ndd->port in mtip_hw_exit() while an ioctl still dereferences it. An already\nopen block device can reach the handlers while del_gendisk() is in\nprogress.\n\nSerialize both native and compat ioctls with removal. Set REMOVE_PENDING\nbefore taking the mutex so new callers fail after an in-flight ioctl has\ndrained, and hold the mutex until the port has been torn down.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/4609e0e0be709e974bec9b52c5022136d25e97d3","https://git.kernel.org/stable/c/521afbd936ac256b7531470b0b9aa96abf9cd853","https://git.kernel.org/stable/c/68940f841d013192086a0f6d7cfbac2cd079e228","https://git.kernel.org/stable/c/8283049aa5fcb4e84b2b2928b2888903bb8ee12e","https://git.kernel.org/stable/c/8a7799597bd683b6bc251fe2edfa9fd1db568a3a"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90180","score":0.00211,"percentile":0.11297,"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).
