If that QP is\nalready in RTS, the function jumps to error cleanup before associating\nthe incoming CEP with it.\n\nThe cleanup tests whether qp->cep is non-NULL and assumes the current\ncall installed the association. However, qp->cep can point to the CEP\nof an existing connection. The cleanup then drops a reference from the\nincoming cep, not qp->cep. Once the incoming endpoint loses its\nremaining references, this can free it before the subsequent cep->qp\nstore, causing a use-after-free. It also clears the existing QP\nassociation.\n\nOnly release the association reference when qp->cep is the incoming\nCEP. This preserves an existing association and avoids accessing the\nfreed endpoint.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/561651d6a15588cee2040755f253faca2463415c","https://git.kernel.org/stable/c/59de5502f32895ffe9c45530327ed997b90fdf06","https://git.kernel.org/stable/c/8f286a8094ee32c415f9ecd2c20765beb8a18c79","https://git.kernel.org/stable/c/a89d120615e711ce8fce551fd291c2f387666735","https://git.kernel.org/stable/c/a9394971825933074032794a5feee5211509c774"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90292","score":0.00164,"percentile":0.05551,"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).
