If a REQ_ATOMIC write encounters a\nbadblock within the requested range, the code jumps to err_handle\nwithout dropping the reference taken for the current mirror.\n\nerr_handle's cleanup loop will only decrements for k < i and\nr1_bio->bios[k] is non-NULL. The current slot is therefore skipped,\nleaving its nr_pending reference leaked permanently. The reference\nprevents the rdev from ever being removed, since raid1_remove_conf()\nrefuses to remove an rdev with nr_pending > 0.\n\nFix this by calling rdev_dec_pending() before jumping to err_handle.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/5ac9e793ba2583d72740d929e7858a6c82e22ed5","https://git.kernel.org/stable/c/731485617bf862f1289c3f40ed1f800d0475826f","https://git.kernel.org/stable/c/909d9dc3b5730c8ed7b764c68bc788342df2a07b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-74372","score":0.00206,"percentile":0.10749,"date":"2026-10-31"},"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).
