This new function enables ring-buffer\nbuffer_data_read_page users to not call the racy\nring_buffer_subbuf_size_get(). This makes the spare_size member of\nftrace_buffer_info redundant.\n\nFinally, handle buffer_data_read_page/reader_page order discrepancy in\nring_buffer_read_page(). On a mismatch simply copy manually the data to\nthe buffer_data_read_page.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3f30b2cd4eba45c05f822f03f1b0f4077d6d4dc3","https://git.kernel.org/stable/c/574efd988d116bd56ac688ab2d64e06ba0da982a","https://git.kernel.org/stable/c/75b37b8369778b69ce9738d1c97685a1615cb252","https://git.kernel.org/stable/c/dae8dda341d2d9034a90d59e8a7d502e1263813f"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98032","score":0.00168,"percentile":0.05987,"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).
