When\nwrite_adapter_mem() fails, it returns the error without releasing the index\nor reversing the statistic.  No MR is inserted into rhp->mrs, so\nderegistration never reclaims it, leaking the index until device teardown.\n\nRecord whether this call allocated the index and, on a failed write, return\nit to tpt_table and decrement stats.stag.cur.  Key the rollback on both the\nwrite error and that flag, not the error alone: a non-reset update carries\na caller-owned STAG that this call did not allocate and must not free.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2f17ca7ab5269ac2504e1039c3921373dccd7712","https://git.kernel.org/stable/c/5a21e5114cec4cd3f8a2843d4c46bc49634d6e96","https://git.kernel.org/stable/c/5fe4731bfbd8d83c4a14b4af3a27329969ce8a99","https://git.kernel.org/stable/c/8f6976d635d190e3d7af7103daaa581cf1ccc12e","https://git.kernel.org/stable/c/9eeafcda1d6c11f0eec532243c4e96ec8c632bd7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90415","score":0.00177,"percentile":0.07157,"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).
