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-2026-53055 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-2026-53055/ (Markdown: https://insights.sbomify.com/CVE-2026-53055/index.md)","id":"CVE-2026-53055","markdown":"https://insights.sbomify.com/CVE-2026-53055/index.md","name":"CVE-2026-53055","record":{"aliases":["BELL-CVE-2026-53055","DEBIAN-CVE-2026-53055","GHSA-22hh-g7wj-354w","UBUNTU-CVE-2026-53055"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel crypto driver","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel's Hisilicon SEC2 crypto driver allows attackers to cause denial of service or execute code under heavy load.","user_interaction":"not_required","vuln_class":"use_after_free"},"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-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: hisilicon/sec2 - prevent req used-after-free for sec\n\nDuring packet transmission, if the system is under heavy load,\nthe hardware might complete processing the packet and free the\nrequest memory (req) before the transmission function finishes.\nIf the software subsequently accesses this req, a use-after-free\nerror will occur.
