Extend the\nexisting verifier allowed-program-type check for updating sockmap/sockhash\nto also cover deleting from a map.\n\nFrom now on only BPF programs which were previously allowed to update\nsockmap/sockhash can delete from these map types.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:N","score":4.7},"cwes":[],"references":["https://git.kernel.org/stable/c/000a65bf1dc04fb2b65e2abf116f0bc0fc2ee7b1","https://git.kernel.org/stable/c/11e8ecc5b86037fec43d07b1c162e233e131b1d9","https://git.kernel.org/stable/c/29467edc23818dc5a33042ffb4920b49b090e63d","https://git.kernel.org/stable/c/6693b172f008846811f48a099f33effc26068e1e","https://git.kernel.org/stable/c/98e948fb60d41447fd8d2d0c3b8637fc6b6dc26d"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2024-38662","score":0.00222,"percentile":0.12597,"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).
