Since if_id can be any 16-bit value (0-65535) but the ports\narray is only allocated with sw_attr.num_ifs elements, this can lead to\nan out-of-bounds read potentially.\n\nAdd a bounds check before accessing the array, consistent with the\nexisting validation in dpaa2_switch_rx().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.0},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/1b381a638e1851d8cfdfe08ed9cdbec5295b18c9","https://git.kernel.org/stable/c/2447edc367800ba914acf7ddd5d250416b45fb31","https://git.kernel.org/stable/c/31a7a0bbeb006bac2d9c81a2874825025214b6d8","https://git.kernel.org/stable/c/34b56c16efd61325d80bf1d780d0e176be662f59","https://git.kernel.org/stable/c/77611cab5bdfff7a070ae574bbfba20a1de99d1b"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-23180","score":0.00143,"percentile":0.03565,"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).
