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-2026-53002 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-2026-53002/ (Markdown: https://insights.sbomify.com/CVE-2026-53002/index.md)","id":"CVE-2026-53002","markdown":"https://insights.sbomify.com/CVE-2026-53002/index.md","name":"CVE-2026-53002","record":{"aliases":["BELL-CVE-2026-53002","DEBIAN-CVE-2026-53002","GHSA-2256-5c36-mwcj","ROOT-OS-DEBIAN-11-CVE-2026-53002","ROOT-OS-DEBIAN-12-CVE-2026-53002","ROOT-OS-UBUNTU-2204-CVE-2026-53002","ROOT-OS-UBUNTU-2404-CVE-2026-53002","UBUNTU-CVE-2026-53002"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A stack buffer overflow in the Linux kernel's netfilter conntrack module allows attackers to cause a denial of service or potentially execute code via crafted SIP messages.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: conntrack: remove sprintf usage\n\nReplace it with scnprintf, the buffer sizes are expected to be large enough\nto hold the result, no need for snprintf+overflow check.\n\nIncrease buffer size in mangle_content_len() while at it.\n\nBUG: KASAN: stack-out-of-bounds in vsnprintf+0xea5/0x1270\nWrite of size 1 at addr [..]\n vsnprintf+0xea5/0x1270\n sprintf+0xb1/0xe0\n mangle_content_len+0x1ac/0x280\n nf_nat_sdp_session+0x1cc/0x240\n process_sdp+0x8f8/0xb80\n process_invite_request+0x108/0x2b0\n process_sip_msg+0x5da/0xf50\n sip_help_tcp+0x45e/0x780\n nf_confirm+0x34d/0x990\n [..]","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":"netfilter: conntrack: remove sprintf usage","id":"CVE-2026-53002","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel","redhat:enterprise_linux"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"pppoe: drop PFC frames","id":"CVE-2026-53003"},"packages":[],"prev":{"headline":"netfilter: xtables: restrict several matches to inet family","id":"CVE-2026-53001"},"products":["Linux"],"published":"2026-06-24","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A stack buffer overflow in the Linux kernel's netfilter conntrack module allows attackers to cause a denial of service or potentially execute code via crafted SIP messages.","url":"https://insights.sbomify.com/CVE-2026-53002/"}
