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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/mellanox/mlx5/core/fs_core.c"],"versions":[{"version":"74491de937125d0c98c9b9c9208b4105717a3caa","lessThan":"de0139719cdda82806a47580ca0df06fc85e0bd2","status":"affected","versionType":"git"},{"version":"74491de937125d0c98c9b9c9208b4105717a3caa","lessThan":"1263b0b26077b1183c3c45a0a2479573a351d423","status":"affected","versionType":"git"},{"version":"74491de937125d0c98c9b9c9208b4105717a3caa","lessThan":"3d90ca9145f6b97b38d0c2b6b30f6ca6af9c1801","status":"affected","versionType":"git"},{"version":"74491de937125d0c98c9b9c9208b4105717a3caa","lessThan":"7aaee12b804c5e0374e7b132b6ec2158ff33dd64","status":"affected","versionType":"git"},{"version":"74491de937125d0c98c9b9c9208b4105717a3caa","lessThan":"2e8dc5cffc844dacfa79f056dea88002312f253f","status":"affected","versionType":"git"},{"version":"74491de937125d0c98c9b9c9208b4105717a3caa","lessThan":"5cf5337ef701830f173b4eec00a4f984adeb57a0","status":"affected","versionType":"git"},{"version":"74491de937125d0c98c9b9c9208b4105717a3caa","lessThan":"adf67a03af39095f05d82050f15813d6f700159d","status":"affected","versionType":"git"},{"version":"74491de937125d0c98c9b9c9208b4105717a3caa","lessThan":"7c6782ad4911cbee874e85630226ed389ff2e453","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/mellanox/mlx5/core/fs_core.c"],"versions":[{"version":"4.10","status":"affected"},{"version":"0","lessThan":"4.10","status":"unaffected","versionType":"semver"},{"version":"4.19.313","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.275","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.216","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.156","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.87","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.28","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.8.7","lessThanOrEqual":"6.8.*","status":"unaffected","versionType":"semver"},{"version":"6.9","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"4.19.313"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"5.4.275"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"5.10.216"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"5.15.156"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"6.1.87"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"6.6.28"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"6.8.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"6.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/de0139719cdda82806a47580ca0df06fc85e0bd2"},{"url":"https://git.kernel.org/stable/c/1263b0b26077b1183c3c45a0a2479573a351d423"},{"url":"https://git.kernel.org/stable/c/3d90ca9145f6b97b38d0c2b6b30f6ca6af9c1801"},{"url":"https://git.kernel.org/stable/c/7aaee12b804c5e0374e7b132b6ec2158ff33dd64"},{"url":"https://git.kernel.org/stable/c/2e8dc5cffc844dacfa79f056dea88002312f253f"},{"url":"https://git.kernel.org/stable/c/5cf5337ef701830f173b4eec00a4f984adeb57a0"},{"url":"https://git.kernel.org/stable/c/adf67a03af39095f05d82050f15813d6f700159d"},{"url":"https://git.kernel.org/stable/c/7c6782ad4911cbee874e85630226ed389ff2e453"}],"title":"net/mlx5:
