This function\nuses the skb_cow_head() to ensure that there is sufficient headroom in\nthe sk_buff for accommodating the link-layer header.\nIn the event that the skb_cow_header() function fails, the\nseg6_input_core() catches the error but it does not release the sk_buff,\nwhich will result in a memory leak.\n\nThis issue was introduced in commit af3b5158b89d (\"ipv6: sr: fix BUG due\nto headroom too small after SRH push\") and persists even after commit\n7a3f5b0de364 (\"netfilter: add netfilter hooks to SRv6 data plane\"),\nwhere the entire seg6_input() code was refactored to deal with netfilter\nhooks.\n\nThe proposed patch addresses the identified memory leak by requiring the\nseg6_input_core() function to release the sk_buff in the event that\nskb_cow_head() fails."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["net/ipv6/seg6_iptunnel.c"], "versions": [{"version": "af3b5158b89d3bab9be881113417558c71b71ca4", "lessThan": "e8688218e38111ace457509d8f0cad75f79c1a7a", "status": "affected", "versionType": "git"}, {"version": "af3b5158b89d3bab9be881113417558c71b71ca4", "lessThan": "8f1fc3b86eaea70be6abcae2e9aa7e7b99453864", "status": "affected", "versionType": "git"}, {"version": "af3b5158b89d3bab9be881113417558c71b71ca4", "lessThan": "f4df8c7670a73752201cbde215254598efdf6ce8", "status": "affected", "versionType": "git"}, {"version": "af3b5158b89d3bab9be881113417558c71b71ca4", "lessThan": "f5fec1588642e415a3d72e02140160661b303940", "status": "affected", "versionType": "git"}, {"version": "af3b5158b89d3bab9be881113417558c71b71ca4", "lessThan": "5447f9708d9e4c17a647b16a9cb29e9e02820bd9", "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/ipv6/seg6_iptunnel.c"], "versions": [{"version": "4.12", "status": "affected"}, {"version": "0", "lessThan": "4.12", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.161", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.93", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.33", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.9.4", "lessThanOrEqual": "6.9.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.10", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "references": [{"url": "https://git.kernel.org/stable/c/e8688218e38111ace457509d8f0cad75f79c1a7a"}, {"url": "https://git.kernel.org/stable/c/8f1fc3b86eaea70be6abcae2e9aa7e7b99453864"}, {"url": "https://git.kernel.org/stable/c/f4df8c7670a73752201cbde215254598efdf6ce8"}, {"url": "https://git.kernel.org/stable/c/f5fec1588642e415a3d72e02140160661b303940"}, {"url": "https://git.kernel.org/stable/c/5447f9708d9e4c17a647b16a9cb29e9e02820bd9"}], "title": "ipv6: sr: fix missing sk_buff release in seg6_input_core", "x_generator": {"engine": "bippy-5f407fcff5a0"}}, "adp": [{"problemTypes": [{"descriptions": [{"type": "CWE", "cweId": "CWE-401", "lang": "en", "description": "CWE-401 Missing Release of Memory after Effective Lifetime"}]}], "metrics": [{"cvssV3_1": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 6.2, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "NONE", "privilegesRequired": "NONE", "confidentialityImpact": "HIGH"}}, {"other": {"type": "ssvc", "content": {"timestamp": "2024-07-11T18:24:36.803451Z", "id": "CVE-2024-39490", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"Technical Impact": "partial"}], "role": "CISA Coordinator", "version": "2.0.3"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-11-25T19:15:34.027Z"}}, {"providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T04:26:15.676Z"}, "title": "CVE Program Container", "references": [{"url": "https://git.kernel.org/stable/c/e8688218e38111ace457509d8f0cad75f79c1a7a", "tags": ["x_transferred"]}, {"url": "https://git.kernel.org/stable/c/8f1fc3b86eaea70be6abcae2e9aa7e7b99453864", "tags": ["x_transferred"]}, {"url": "https://git.kernel.org/stable/c/f4df8c7670a73752201cbde215254598efdf6ce8", "tags": ["x_transferred"]}, {"url": "https://git.kernel.org/stable/c/f5fec1588642e415a3d72e02140160661b303940", "tags": ["x_transferred"]}, {"url": "https://git.kernel.org/stable/c/5447f9708d9e4c17a647b16a9cb29e9e02820bd9", "tags": ["x_transferred"]}]}]}}
