"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmlxsw: spectrum_flower: Fix port range register leak in tmplt_create()\n\nmlxsw_sp_flower_tmplt_create() parses a flow_cls_offload template\ninto a stack-local struct mlxsw_sp_acl_rule_info purely to compute\nrulei.values.elusage. 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."
