It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2015-3636 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2015-3636/ (Markdown: https://insights.sbomify.com/CVE-2015-3636/index.md)","id":"CVE-2015-3636","markdown":"https://insights.sbomify.com/CVE-2015-3636/index.md","name":"CVE-2015-3636","record":{"aliases":["DEBIAN-CVE-2015-3636","GHSA-67pv-68g5-4j93","RHSA-2015:1583","RHSA-2015:1643","UBUNTU-CVE-2015-3636"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Local attackers can exploit a use-after-free in the Linux kernel ping implementation to escalate privileges or crash the system.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":4.9,"severity":"medium","source":"nvd","vector":"AV:L/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[],"description":"The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a certain list data structure during an unhash operation, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6 protocol, and then making a connect system call after a disconnect.","ecosystems":["Red Hat:rhel_aus:6.4::server","Red Hat:rhel_eus:6.5::computenode","Red Hat:rhel_eus:6.5::server"],"exploits":{"exploitdb":0,"first_seen":"2015-07-25","github_poc":7,"max_poc_stars":136,"metasploit":0,"nuclei":0,"refs":[{"date":"2015-09-12T01:31:36Z","kind":"github_poc","ref":"https://github.com/fi01/CVE-2015-3636","stars":136,"title":"PoC code for 32 bit Android OS"},{"date":"2015-10-07T12:54:57Z","kind":"github_poc","ref":"https://github.com/android-rooting-tools/libpingpong_exploit","stars":45,"title":"CVE-2015-3636 exploit "},{"date":"2017-01-02T02:59:29Z","kind":"github_poc","ref":"https://github.com/a7vinx/CVE-2015-3636","stars":20,"title":"Expolit for android (goldfish kernel v3.10.0+) on arm64 with PXN\u0026SELinux Bypassed.
