As a result, it leads to slab\nout-of-bound access.\nThis patch adds back the IP_SET_HASH_WITH_NET0 macro to\nip_set_hash_netportnet to address the issue.","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-787"],"references":["https://git.kernel.org/stable/c/050d91c03b28ca479df13dfb02bcd2c60dd6a878","https://git.kernel.org/stable/c/109e830585e89a03d554bf8ad0e668630d0a6260","https://git.kernel.org/stable/c/7935b636dd693dfe4483cfef4a1e91366c8103fa","https://git.kernel.org/stable/c/7ca0706c68adadf86a36b60dca090f5e9481e808","https://git.kernel.org/stable/c/83091f8ac03f118086596f17c9a52d31d6ca94b3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:08:41.295252406+00:00"},"epss":{"cve":"CVE-2023-53179","score":0.00171,"percentile":0.06476,"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).
