It is created only\nwhen vport metadata match and prio tag are enabled. But active-backup\nlag mode also uses it. It is independent of vport metadata match and\nprio tag. And vport metadata match can be disabled using the\nfollowing devlink command:\n\n # devlink dev param set pci/0000:08:00.0 name esw_port_metadata \\\n\tvalue false cmode runtime\n\nIf ingress acl is not created, will hit panic when creating drop rule\nfor active-backup lag mode. If always create it, there will be about\n5% performance degradation.\n\nFix it by creating ingress acl when needed. If esw_port_metadata is\ntrue, ingress acl exists, then create drop rule using existing\ningress acl. If esw_port_metadata is false, create ingress acl and\nthen create drop rule."}],"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/esw/acl/ingress_ofld.c"],"versions":[{"version":"1749c4c51c16e3e078faae0a876d01bafb187a74","lessThan":"bc3ff8d3c05044de57865ebbb78cca8f7da3e595","status":"affected","versionType":"git"},{"version":"1749c4c51c16e3e078faae0a876d01bafb187a74","lessThan":"3e3551f8702978cd2221d2614ca6d6727e785324","status":"affected","versionType":"git"},{"version":"1749c4c51c16e3e078faae0a876d01bafb187a74","lessThan":"83bc1a129f7fd0d7d05036ceb7ee69102624e320","status":"affected","versionType":"git"},{"version":"1749c4c51c16e3e078faae0a876d01bafb187a74","lessThan":"b20c2fb45470d0c7a603613c9cfa5d45720e17f2","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/esw/acl/ingress_ofld.c"],"versions":[{"version":"5.18","status":"affected"},{"version":"0","lessThan":"5.18","status":"unaffected","versionType":"semver"},{"version":"6.1.98","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.39","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.9.9","lessThanOrEqual":"6.9.*","status":"unaffected","versionType":"semver"},{"version":"6.10","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":"5.18","versionEndExcluding":"6.1.98"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.6.39"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.9.9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/bc3ff8d3c05044de57865ebbb78cca8f7da3e595"},{"url":"https://git.kernel.org/stable/c/3e3551f8702978cd2221d2614ca6d6727e785324"},{"url":"https://git.kernel.org/stable/c/83bc1a129f7fd0d7d05036ceb7ee69102624e320"},{"url":"https://git.kernel.org/stable/c/b20c2fb45470d0c7a603613c9cfa5d45720e17f2"}],"title":"net/mlx5: E-switch, Create ingress ACL when needed","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/bc3ff8d3c05044de57865ebbb78cca8f7da3e595","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/3e3551f8702978cd2221d2614ca6d6727e785324","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/83bc1a129f7fd0d7d05036ceb7ee69102624e320","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/b20c2fb45470d0c7a603613c9cfa5d45720e17f2","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T22:02:09.747Z"}},{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-42142","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T16:15:50.447438Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-11T17:34:35.365Z"}}]}}
