An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-27393 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-27393/ (Markdown: https://insights.sbomify.com/CVE-2024-27393/index.md)","id":"CVE-2024-27393","markdown":"https://insights.sbomify.com/CVE-2024-27393/index.md","name":"CVE-2024-27393","record":{"aliases":["BELL-CVE-2024-27393","DEBIAN-CVE-2024-27393","GHSA-8r78-c2f2-82qm","ROOT-OS-DEBIAN-11-CVE-2024-27393","UBUNTU-CVE-2024-27393"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A memory leak in the Linux kernel's xen-netfront driver can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nxen-netfront: Add missing skb_mark_for_recycle\n\nNotice that skb_mark_for_recycle() is introduced later than fixes tag in\ncommit 6a5bcd84e886 (\"page_pool: Allow drivers to hint on SKB recycling\").\n\nIt is believed that fixes tag were missing a call to page_pool_release_page()\nbetween v5.9 to v5.14, after which is should have used skb_mark_for_recycle().\nSince v6.6 the call page_pool_release_page() were removed (in\ncommit 535b9c61bdef (\"net: page_pool: hide page_pool_release_page()\")\nand remaining callers converted (in commit 6bfef2ec0172 (\"Merge branch\n'net-page_pool-remove-page_pool_release_page'\")).\n\nThis leak became visible in v6.8 via commit dba1b8a7ab68 (\"mm/page_pool: catch\npage_pool memory leaks\").","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"xen-netfront: Add missing skb_mark_for_recycle","id":"CVE-2024-27393","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":5,"next":{"headline":"tcp: Fix Use-After-Free in tcp_ao_connect_init","id":"CVE-2024-27394"},"packages":[],"prev":{"headline":"nvme: host: fix double-free of struct nvme_id_ns in ns_update_nuse()","id":"CVE-2024-27392"},"products":["Linux"],"published":"2024-05-09","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel's xen-netfront driver can lead to resource exhaustion and denial of service.","url":"https://insights.sbomify.com/CVE-2024-27393/"}
