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-2026-45988 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-2026-45988/ (Markdown: https://insights.sbomify.com/CVE-2026-45988/index.md)","id":"CVE-2026-45988","markdown":"https://insights.sbomify.com/CVE-2026-45988/index.md","name":"CVE-2026-45988","record":{"aliases":["AZL-88475","BELL-CVE-2026-45988","DEBIAN-CVE-2026-45988","GHSA-prrp-jq4x-wwq4","ROOT-OS-DEBIAN-11-CVE-2026-45988","ROOT-OS-DEBIAN-12-CVE-2026-45988","ROOT-OS-UBUNTU-2204-CVE-2026-45988","ROOT-OS-UBUNTU-2404-CVE-2026-45988","UBUNTU-CVE-2026-45988"],"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 flaw in the Linux kernel's rxrpc module allows temporary processing failures to leave packets in an inconsistent state, potentially causing denial of service.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"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-682","name":"Incorrect Calculation"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Fix re-decryption of RESPONSE packets\n\nIf a RESPONSE packet gets a temporary failure during processing, it may end\nup in a partially decrypted state - and then get requeued for a retry.\n\nFix this by just discarding the packet; we will send another CHALLENGE\npacket and thereby elicit a further response.
