On the other hand,\ncreate_flow_handle tries hard to find and reference already existing\nidentical rules instead of creating new ones.\n\nThese two behaviors can result in a situation where create_flow_handle\n1) creates a new rule and references it, then\n2) in a subsequent step during the same handle creation references it\n again,\nresulting in a rule with a refcount of 2 that is not linked into the\ntree, will have a NULL parent and root and will result in a crash when\nthe flow group is deleted because del_sw_hw_rule, invoked on rule\ndeletion, assumes node->parent is != NULL.\n\nThis happened in the wild, due to another bug related to incorrect\nhandling of duplicate pkt_reformat ids, which lead to the code in\ncreate_flow_handle incorrectly referencing a just-added rule in the same\nflow handle, resulting in the problem described above. Full details are\nat [1].\n\nThis patch changes add_rule_fg to add new rules without parents into\nthe tree, properly initializing them and avoiding the crash. This makes\nit more consistent with how rules are added to an FTE in\ncreate_flow_handle."}]}, "problemtype": {"problemtype_data": [{"description": []}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2024-35960", "ASSIGNER": "cve@kernel.org"}}, "impact": {}, "publishedDate": "2024-05-20T10:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.9:rc3:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.9:rc1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.9:rc2:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "5.10.216", "versionStartIncluding": "5.5"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "5.4.275", "versionStartIncluding": "4.20"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "5.15.156", "versionStartIncluding": "5.11"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "4.19.313", "versionStartIncluding": "4.10"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.1.87", "versionStartIncluding": "5.16"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.6.28", "versionStartIncluding": "6.2"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.8.7", "versionStartIncluding": "6.7"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2025-04-04T14:22Z"}
