It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-50219 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-2022-50219/ (Markdown: https://insights.sbomify.com/CVE-2022-50219/index.md)","id":"CVE-2022-50219","markdown":"https://insights.sbomify.com/CVE-2022-50219/index.md","name":"CVE-2022-50219","record":{"aliases":["DEBIAN-CVE-2022-50219","GHSA-f8rq-3pf9-vf74","UBUNTU-CVE-2022-50219"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's BPF subsystem allows attackers to potentially execute arbitrary code or escalate privileges.","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":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/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\nbpf: Fix KASAN use-after-free Read in compute_effective_progs\n\nSyzbot found a Use After Free bug in compute_effective_progs().\nThe reproducer creates a number of BPF links, and causes a fault\ninjected alloc to fail, while calling bpf_link_detach on them.\nLink detach triggers the link to be freed by bpf_link_free(),\nwhich calls __cgroup_bpf_detach() and update_effective_progs().\nIf the memory allocation in this function fails, the function restores\nthe pointer to the bpf_cgroup_link on the cgroup list, but the memory\ngets freed just after it returns.
