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-2026-15813 in the wild and no public exploit code.\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-2026-15813/ (Markdown: https://insights.sbomify.com/CVE-2026-15813/index.md)","id":"CVE-2026-15813","markdown":"https://insights.sbomify.com/CVE-2026-15813/index.md","name":"CVE-2026-15813","record":{"aliases":["AZL-92898","DEBIAN-CVE-2026-15813","GHSA-32vg-vj46-3h6w","UBUNTU-CVE-2026-15813"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kronosnet library","requires_auth":"none","summary":"An attacker can cause application crashes or system instability by sending malformed network packets that trigger out-of-bounds memory access in the packet defragmentation engine.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A vulnerability was found in the network packet de-fragmentation engine of kronosnet (Version affected \u003c= 1.34). The internal reassembly code does not properly validate sequence numbers of incoming payload fragments. An attacker can exploit this lack of verification by transmitting malformed packets with corrupted sequence parameters. Under specific conditions, this forces the packet processing layer to parse data outside the designated bounds of the internal memory structures, causing an out-of-bounds memory access or heap corruption. This behavior can result in sudden application crashes or system instability.","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":"Kronosnet: kronosnet: memory corruption and out-of-bounds access via malformed network packet defragmentation","id":"CVE-2026-15813","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Uploading a crafted image causes excessive memory allocation in the Mattermost Server","id":"CVE-2026-15814"},"packages":[],"prev":{"headline":"Kronosnet: kronosnet: access control list bypass via link id spoofing on unencrypted dynamic links","id":"CVE-2026-15812"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat OpenShift Container Platform 4"],"published":"2026-07-20","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-08-21","vendors":["Red Hat"]},"summary":"An attacker can cause application crashes or system instability by sending malformed network packets that trigger out-of-bounds memory access in the packet defragmentation engine.","url":"https://insights.sbomify.com/CVE-2026-15813/"}
