An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-15711 exists.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2026-15711/ (Markdown: https://insights.sbomify.com/CVE-2026-15711/index.md)","id":"CVE-2026-15711","markdown":"https://insights.sbomify.com/CVE-2026-15711/index.md","name":"CVE-2026-15711","record":{"aliases":["ALSA-2026:68266","AZL-92400","DEBIAN-CVE-2026-15711","ECHO-e22f-3a38-1187","GHSA-w948-qrw5-cffc","OESA-2026-3779","OESA-2026-3780","OESA-2026-3781","RHSA-2026:68266","RLSA-2026:68266","ROOT-OS-DEBIAN-12-CVE-2026-15711","ROOT-OS-DEBIAN-13-CVE-2026-15711","UBUNTU-CVE-2026-15711"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libsoup WebSocket library","requires_auth":"none","summary":"Remote attackers can crash applications using libsoup WebSockets by sending oversized control frames, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"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-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames (e.g., PING, PONG, CLOSE) contain a payload of 125 bytes or less. A remote, unauthenticated attacker can exploit this by sending a non-compliant, oversized control frame. Because the parser handles this protocol violation improperly instead of throwing an immediate connection termination error, it triggers a internal processing crash, resulting in a remote denial of service (DoS) for applications utilizing libsoup WebSockets.","ecosystems":["AlmaLinux:8","Red Hat:enterprise_linux:8::appstream","Red Hat:enterprise_linux:8::baseos","Rocky Linux:8"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in Red Hat Enterprise Linux 10","id":"CVE-2026-15711","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":9,"n_references":13,"next":{"headline":"Memory corruption in Red Hat Enterprise Linux 10","id":"CVE-2026-15712"},"packages":[{"ecosystem":"AlmaLinux:8","fixed":["2.62.3-15.el8_10"],"introduced":["0"],"last_affected":[],"package":"libsoup","purl":"pkg:rpm/almalinux/libsoup","source":"ALSA-2026:68266"},{"ecosystem":"AlmaLinux:8","fixed":["2.62.3-15.el8_10"],"introduced":["0"],"last_affected":[],"package":"libsoup-devel","purl":"pkg:rpm/almalinux/libsoup-devel","source":"ALSA-2026:68266"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:2.62.3-15.el8_10"],"introduced":["0"],"last_affected":[],"package":"libsoup-debuginfo","purl":"pkg:rpm/redhat/libsoup-debuginfo","source":"RHSA-2026:68266"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:2.62.3-15.el8_10"],"introduced":["0"],"last_affected":[],"package":"libsoup-debugsource","purl":"pkg:rpm/redhat/libsoup-debugsource","source":"RHSA-2026:68266"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:2.62.3-15.el8_10"],"introduced":["0"],"last_affected":[],"package":"libsoup-devel","purl":"pkg:rpm/redhat/libsoup-devel","source":"RHSA-2026:68266"},{"ecosystem":"Red Hat:enterprise_linux:8::baseos","fixed":["0:2.62.3-15.el8_10"],"introduced":["0"],"last_affected":[],"package":"libsoup","purl":"pkg:rpm/redhat/libsoup","source":"RHSA-2026:68266"},{"ecosystem":"Red Hat:enterprise_linux:8::baseos","fixed":["0:2.62.3-15.el8_10"],"introduced":["0"],"last_affected":[],"package":"libsoup-debuginfo","purl":"pkg:rpm/redhat/libsoup-debuginfo","source":"RHSA-2026:68266"},{"ecosystem":"Red Hat:enterprise_linux:8::baseos","fixed":["0:2.62.3-15.el8_10"],"introduced":["0"],"last_affected":[],"package":"libsoup-debugsource","purl":"pkg:rpm/redhat/libsoup-debugsource","source":"RHSA-2026:68266"},{"ecosystem":"Rocky Linux:8","fixed":["0:2.62.3-15.el8_10"],"introduced":["0"],"last_affected":[],"package":"libsoup","purl":"pkg:rpm/rocky-linux/libsoup?distro=rocky-linux-8\u0026epoch=0","source":"RLSA-2026:68266"}],"prev":{"headline":"Netskope Client Endpoint DLP Kernel Driver Information Leakage","id":"CVE-2026-15710"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 10.0 Extended Update Support","Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.8 Telecommunications Update Service","Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions","Red Hat Enterprise Linux 9","Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions","Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions","Red Hat Enterprise Linux 9.6 Extended Update Support"],"published":"2026-07-14","related":[],"sources":[{"class":"attribution","licence":"MIT","name":"AlmaLinux","prefix":"ALSA"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"class":"attribution","licence":"BSD","name":"Rocky Linux","prefix":"RLSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["Red Hat"]},"summary":"Remote attackers can crash applications using libsoup WebSockets by sending oversized control frames, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2026-15711/"}
