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-2022-50764 in the wild and no public exploit code.\n\nAffected product: 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-2022-50764/ (Markdown: https://insights.sbomify.com/CVE-2022-50764/index.md)","id":"CVE-2022-50764","markdown":"https://insights.sbomify.com/CVE-2022-50764/index.md","name":"CVE-2022-50764","record":{"aliases":["DEBIAN-CVE-2022-50764","GHSA-grmr-47cc-4gc2","ROOT-OS-DEBIAN-11-CVE-2022-50764","UBUNTU-CVE-2022-50764"],"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 race condition in the Linux kernel's IPv6 SIT tunnel driver can cause concurrent updates to error statistics, potentially leading to system instability or denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nipv6/sit: use DEV_STATS_INC() to avoid data-races\n\nsyzbot/KCSAN reported that multiple cpus are updating dev-\u003estats.tx_error\nconcurrently.\n\nThis is because sit tunnels are NETIF_F_LLTX, meaning their ndo_start_xmit()\nis not protected by a spinlock.\n\nWhile original KCSAN report was about tx path, rx path has the same issue.","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":"ipv6/sit: use DEV_STATS_INC() to avoid data-races","id":"CVE-2022-50764","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2022"},"n_packages":0,"n_references":4,"next":{"headline":"RISC-V: kexec: Fix memory leak of elf header buffer","id":"CVE-2022-50765"},"packages":[],"prev":{"headline":"crypto: marvell/octeontx - prevent integer overflows","id":"CVE-2022-50763"},"products":["Linux"],"published":"2025-12-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A race condition in the Linux kernel's IPv6 SIT tunnel driver can cause concurrent updates to error statistics, potentially leading to system instability or denial of service.","url":"https://insights.sbomify.com/CVE-2022-50764/"}
