Go ahead and remove the\nsun8i-ce support which is one of the only remaining ones.\n\nNote that the sun8i-ce support for hwrng remains in place.  That is the\ninterface that actually matters.\n\nAs usual for crypto_rng, this driver was also buggy: its ->generate()\nfunction had a use-after-free vulnerability due to using\nwait_for_completion_interruptible_timeout() without handling shutting\ndown the DMA operation if a signal is sent.  There's no point in fixing\nthis separately only to remove the code anyway, so this commit is marked\nwith Fixes and Cc stable.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/011556f71d094da61379ae3672692cae2795304e","https://git.kernel.org/stable/c/1017f987c5f0841f00408a78f947990c9d84b346","https://git.kernel.org/stable/c/19588f78db582ba4c47b4001bb27f39bb19dc432","https://git.kernel.org/stable/c/2c8fa2299789282db1aac566a60c2012a5ba8ea8","https://git.kernel.org/stable/c/7bb9e6060710eb7b59491d9826169190297adace"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80834","score":0.00177,"percentile":0.07171,"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).
