If discard reuses an\nr10bio that was previously used for a read, read_slot can still be\nnon-negative, and discard cleanup can skip bio_put() on repl_bio.\n\nReset read_slot to -1 when preparing an r10bio for discard so the\nreplacement bio is always released correctly.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":[],"references":["https://git.kernel.org/stable/c/3cb2a606ce4902eceabe68338df0653312f861f8","https://git.kernel.org/stable/c/561c9711e4f545d6464a023168bdee03b00fa945","https://git.kernel.org/stable/c/6b8a26af065ddc93de2aa5c9f0df98dce9723442","https://git.kernel.org/stable/c/742e4afd247d9c972695227716b03d432a7e1d26","https://git.kernel.org/stable/c/b7313f23ea5a79b199a007bfad64a866cc2c22e7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-74376","score":0.00502,"percentile":0.42697,"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).
