Parsing can acquire port range registers via\nmlxsw_sp_flower_parse_ports_range(), but since this rulei never goes\nthrough mlxsw_sp_acl_rulei_destroy(), those registers were never\nreleased, including through chain template deletion.\n\nFactor out of mlxsw_sp_acl_rulei_destroy() the code to actually\nrelease the necessary resources and call from\nmlxsw_sp_flower_tmplt_create() to plug the leak.\n\nThe issue was found during a review of Wentao Liang's patch referenced\nbelow.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3938430f0237c59ca08d6a366e7657b2b7f8d0bb","https://git.kernel.org/stable/c/41ad5bcf0219aaebf8ffb052c5e8177479330cde","https://git.kernel.org/stable/c/4eaf1285b5c1e42f80e47f9fe0d391e70418db02","https://git.kernel.org/stable/c/7ea07afb230f1342ab0f9365edd0aae137f425d3","https://git.kernel.org/stable/c/c8e934287debb29c6ded86b21e49fc72e186d15e"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-98948","score":0.00168,"percentile":0.06111,"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).
