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.","state":0,"publishedAt":"2024-05-20T09:41:51.9+00:00","modifiedAt":"2026-10-15T00:41:43.217+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/ethernet/mellanox/mlx5/core/fs_core.c\"\n ],\n \"versions\": [\n {\n \"version\": \"74491de937125d0c98c9b9c9208b4105717a3caa\",\n \"lessThan\": \"de0139719cdda82806a47580ca0df06fc85e0bd2\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"74491de937125d0c98c9b9c9208b4105717a3caa\",\n \"lessThan\": \"1263b0b26077b1183c3c45a0a2479573a351d423\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"74491de937125d0c98c9b9c9208b4105717a3caa\",\n \"lessThan\": \"3d90ca9145f6b97b38d0c2b6b30f6ca6af9c1801\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"74491de937125d0c98c9b9c9208b4105717a3caa\",\n \"lessThan\": \"7aaee12b804c5e0374e7b132b6ec2158ff33dd64\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"74491de937125d0c98c9b9c9208b4105717a3caa\",\n \"lessThan\": \"2e8dc5cffc844dacfa79f056dea88002312f253f\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"74491de937125d0c98c9b9c9208b4105717a3caa\",\n \"lessThan\": \"5cf5337ef701830f173b4eec00a4f984adeb57a0\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"74491de937125d0c98c9b9c9208b4105717a3caa\",\n \"lessThan\": \"adf67a03af39095f05d82050f15813d6f700159d\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"74491de937125d0c98c9b9c9208b4105717a3caa\",\n \"lessThan\": \"7c6782ad4911cbee874e85630226ed389ff2e453\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/ethernet/mellanox/mlx5/core/fs_core.c\"\n ],\n \"versions\": [\n {\n \"version\": \"4.10\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"4.10\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"4.19.313\",\n \"lessThanOrEqual\": \"4.19.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.4.275\",\n \"lessThanOrEqual\": \"5.4.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.216\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.156\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.87\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.28\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.8.7\",\n \"lessThanOrEqual\": \"6.8.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.9\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/de0139719cdda82806a47580ca0df06fc85e0bd2","https://git.kernel.org/stable/c/1263b0b26077b1183c3c45a0a2479573a351d423","https://git.kernel.org/stable/c/3d90ca9145f6b97b38d0c2b6b30f6ca6af9c1801","https://git.kernel.org/stable/c/7aaee12b804c5e0374e7b132b6ec2158ff33dd64","https://git.kernel.org/stable/c/2e8dc5cffc844dacfa79f056dea88002312f253f","https://git.kernel.org/stable/c/5cf5337ef701830f173b4eec00a4f984adeb57a0","https://git.kernel.org/stable/c/adf67a03af39095f05d82050f15813d6f700159d","https://git.kernel.org/stable/c/7c6782ad4911cbee874e85630226ed389ff2e453"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-35960","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-35960","identifiers":["CVE-2024-35960"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
