If the subsequent allocation or creation of\nregular TX queues fails, the error handling paths omit the teardown of the\nXDP TX queues, leading to a resource leak.\n\nFix this by explicitly destroying the XDP TX queue subset at the two\nmissing failure points.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still\npresent in v7.1-rc7.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have\nan ENA device to test with, no runtime testing was able to be performed."}], "id": "CVE-2026-72056", "lastModified": "2026-11-06T17:19:35.683", "metrics": {"ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2026-72056", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2026-11-06T16:50:49.555392Z", "version": "2.0.3"}}]}, "published": "2026-08-15T06:21:15.010", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/11f68ebc6891d11de5f32b7dee918c5dc18b8de1"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/1bd6676254b4ab6acd44b662b5e92822c036463a"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/523caef03124ecc08ce62a78c617759c2d28cf1c"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/5daa63404b708fc74e94da8398affbb148d09044"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/6596baf8041100a9d1647beb5ea8ea4496ce058f"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/6773d6d82bdabddab2b31605d6d7029c91dbd217"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/df65d9fea8437235e740552e542fb309765507db"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/f2ff634d95f8a6c885b9ce71a64067e255bcc34a"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Received"}
