However, in\nrocker_world_port_post_fini(), the memory is only freed when\nwops->port_post_fini callback is set:\n\n    if (!wops->port_post_fini)\n        return;\n    wops->port_post_fini(rocker_port);\n    kfree(rocker_port->wpriv);\n\nSince rocker_ofdpa_ops does not implement port_post_fini callback\n(it is NULL), the wpriv memory allocated for each port is never freed\nwhen ports are removed. This leads to a memory leak of\nsizeof(struct ofdpa_port) bytes per port on every device removal.\n\nFix this by always calling kfree(rocker_port->wpriv) regardless of\nwhether the port_post_fini callback exists.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/2a3a64d75d2d0727da285749476761ebcad557a3","https://git.kernel.org/stable/c/8ce2e85889939c02740b4245301aa5c35fc94887","https://git.kernel.org/stable/c/8d7ba71e46216b8657a82ca2ec118bc93812a4d0","https://git.kernel.org/stable/c/b11e6f926480ab0939fec44781f28558c54be4e7","https://git.kernel.org/stable/c/d448bf96889f1905e740c554780f5c9fa0440566"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-23164","score":0.00177,"percentile":0.07237,"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).
