There can be a pending tasklet in\nthe queue which might run after the cvm_oct_remove() frees net_device\nstructures, causing a use-after-free in cvm_oct_tx_do_cleanup() as it\niterates cvm_oct_device[] which is an array of netdevice pointers.\nAdd tasklet_kill() after free_irq() to ensure the tasklet is no longer\nscheduled or running before teardown proceeds.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/03d12490afd1198310ad0aba42462329832eb739","https://git.kernel.org/stable/c/2c0c9956596e48654bb4855e2a0742748a0826a7","https://git.kernel.org/stable/c/32efcb6d5f4e3f030e7b0a3ba5c6c0684dd07486","https://git.kernel.org/stable/c/41a79bd9e5a74f8f483b3b206d10567912874fb4","https://git.kernel.org/stable/c/a77efd85e0d48c877f66d2bc3ab89cc1b8dacd19"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-93279","score":0.00196,"percentile":0.09234,"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).
