The netns exit path does not stop these sockets, so a namespace\ncan be torn down while its SCTP UDP tunnel sockets are still installed.\n\nClose the UDP tunnel sockets from sctp_ctrlsock_exit() after unregistering\nthe per-net sysctl table. This prevents new sysctl writes from racing in\nwhile the sockets are being released, and closes the sockets before the\ncontrol socket is destroyed."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["net/sctp/protocol.c"], "versions": [{"version": "046c052b475e7119b6a30e3483e2888fc606a2f8", "lessThan": "c6eb2d615210b80339548ab07c0230edaab9a6c7", "status": "affected", "versionType": "git"}, {"version": "046c052b475e7119b6a30e3483e2888fc606a2f8", "lessThan": "8ff78591d309c50a4fdab683b68dd8d512a270dd", "status": "affected", "versionType": "git"}, {"version": "046c052b475e7119b6a30e3483e2888fc606a2f8", "lessThan": "3bf0e349cbb4f975f35eb22753acc346b89c66a0", "status": "affected", "versionType": "git"}, {"version": "046c052b475e7119b6a30e3483e2888fc606a2f8", "lessThan": "37ff9794be48d0caa37687e04d09675f9c849121", "status": "affected", "versionType": "git"}, {"version": "046c052b475e7119b6a30e3483e2888fc606a2f8", "lessThan": "ffb2bd7ade36ec4da32c46a6eddbf4515316d08c", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["net/sctp/protocol.c"], "versions": [{"version": "5.11", "status": "affected"}, {"version": "0", "lessThan": "5.11", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.151", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.101", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.42", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.6", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2-rc5", "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": "5.11", "versionEndExcluding": "6.6.151"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.11", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.11", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.11", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.11", "versionEndExcluding": "7.2-rc5"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/c6eb2d615210b80339548ab07c0230edaab9a6c7"}, {"url": "https://git.kernel.org/stable/c/8ff78591d309c50a4fdab683b68dd8d512a270dd"}, {"url": "https://git.kernel.org/stable/c/3bf0e349cbb4f975f35eb22753acc346b89c66a0"}, {"url": "https://git.kernel.org/stable/c/37ff9794be48d0caa37687e04d09675f9c849121"}, {"url": "https://git.kernel.org/stable/c/ffb2bd7ade36ec4da32c46a6eddbf4515316d08c"}], "title": "sctp: close UDP tunnel sockets during netns teardown", "x_generator": {"engine": "bippy-1.2.0"}}}}
