If the allocation\nfails, the driver unwinds the port while its console remains registered.\nThe earlier uport->name allocation has a related failure path that leaves\nstate->uart_port linked to a port being freed.\n\nFailslab reproduced a NULL dereference in PL011 console output and a KASAN\nuse-after-free in i.MX console output after failed binds.\n\nAllocate the name and tty_groups before linking the port and configuring\nit. Reserve space for the optional driver attribute group because\nconfig_port() may populate uport->attr_group during configuration.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1a0e4fbce5d9c1bc179a35a2fd9ed142664299e3","https://git.kernel.org/stable/c/8c7c75bfa7b84d6999de2100ce9c09e3779249a0","https://git.kernel.org/stable/c/9260a92ce90e6a95ce2ffdf1441c5216bf3f9552","https://git.kernel.org/stable/c/c2aec15f78b2e6ccd9b94216a901248511355982","https://git.kernel.org/stable/c/e2ddbfd826836cba1b7a25ee4eb512f7d752b703"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-90337","score":0.00209,"percentile":0.10935,"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).
