If we have called tcf_mirred_forward(), however, the skb\nis out of our hands and returning SHOT will lead to UaF.\n\nMove the retval override to the error path which actually need it.","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":["CWE-416"],"references":["https://git.kernel.org/stable/c/0117fe0a4615a7c8d30d6ebcbf87332fbe63e6fd","https://git.kernel.org/stable/c/166c2c8a6a4dc2e4ceba9e10cfe81c3e469e3210","https://git.kernel.org/stable/c/28cdbbd38a4413b8eff53399b3f872fd4e80db9d","https://git.kernel.org/stable/c/9d3ef89b6a5e9f2e940de2cef3d543be0be8dec5","https://git.kernel.org/stable/c/e873e8f7d03a2ee5b77fb1a305c782fed98e2754"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:47:51.568503435+00:00"},"epss":{"cve":"CVE-2024-26739","score":0.00278,"percentile":0.20289,"date":"2026-11-01"},"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).
