When an allocation fails, the previously\nsuccessful allocations are not freed on exit.\n\nFix that by jumping to err_free_rings label on error, which calls\nrtl8180_free_rx_ring() to free the allocations. Remove the free of\nrx_ring in rtl8180_init_rx_ring() error path, and set the freed\npriv->rx_buf entry to null, to avoid double free.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3677c01891fb0239361e444afee8398868e34bdf","https://git.kernel.org/stable/c/89caaeee8dd95fae8bb4f4964e6fe3ca688500c4","https://git.kernel.org/stable/c/9b5b9c042b30befc5b37e4539ace95af70843473","https://git.kernel.org/stable/c/a4fb7cca9837378878e6c94d9e7af019c8fdfcdb","https://git.kernel.org/stable/c/a813a74570212cb5f3a7d3b05c0cb0cd00bace1d"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2025-68759","score":0.00198,"percentile":0.09463,"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).
