If an\ninterrupt fires after usbhs_pipe_remove() but before the driver is fully\nunbound, the ISR may access freed memory, causing a use-after-free.\n\nFix this by calling devm_free_irq() before freeing resources. This ensures\nthe interrupt handler is both disabled and synchronized (waits for any\nrunning ISR to complete) before usbhs_pipe_remove() is called.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/0b7d11fd6e742ecc0b1eca44b4f0b93140c74bae","https://git.kernel.org/stable/c/1899edac312ef17a7234851686e8a703f56d0a84","https://git.kernel.org/stable/c/3cbc242b88c607f55da3d0d0d336b49bf1e20412","https://git.kernel.org/stable/c/51afaf919bbaacdd9cc9e146033ae0a743a42dd7","https://git.kernel.org/stable/c/6287e0c01ccb818e7214f88d885ffb7c9e81b0e0"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-43426","score":0.00126,"percentile":0.02228,"date":"2026-10-31"},"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).
