As the free_irq only waits\nfor completion of hard interrupt handlers, the napi poll\nfunction could still be active. If cvm_oct_remove proceeds to\nfree the plat structure (which holds the NAPI instances), the\nactive poll function will access freed memory, resulting in a\nuse-after-free crash.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/158389d7af04bbf0664d91c2ce31fcc9eeace1eb","https://git.kernel.org/stable/c/89f9f433271fad9351de6a3c713b45b2cfb23e4a","https://git.kernel.org/stable/c/98f9036b2254c928cb44da0c77dba38f66f7d8f1","https://git.kernel.org/stable/c/b2243ffaac14cc3639b5b32a371aac37f96ee554","https://git.kernel.org/stable/c/b38fbd68cc36b4f478a1e3cfc169b8616ae1337d"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-93278","score":0.00192,"percentile":0.08731,"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).
