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-2022-50426 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-2022-50426/ (Markdown: https://insights.sbomify.com/CVE-2022-50426/index.md)","id":"CVE-2022-50426","markdown":"https://insights.sbomify.com/CVE-2022-50426/index.md","name":"CVE-2022-50426","record":{"aliases":["DEBIAN-CVE-2022-50426","GHSA-w4mq-qvfm-cqjm","UBUNTU-CVE-2022-50426"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel's i.MX DSP remoteproc driver can cause a kernel crash when workqueue tasks access released resources.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nremoteproc: imx_dsp_rproc: Add mutex protection for workqueue\n\nThe workqueue may execute late even after remoteproc is stopped or\nstopping, some resources (rpmsg device and endpoint) have been\nreleased in rproc_stop_subdevices(), then rproc_vq_interrupt()\naccessing these resources will cause kennel dump.\n\nCall trace:\n virtqueue_add_split+0x1ac/0x560\n virtqueue_add_inbuf+0x4c/0x60\n rpmsg_recv_done+0x15c/0x294\n vring_interrupt+0x6c/0xa4\n rproc_vq_interrupt+0x30/0x50\n imx_dsp_rproc_vq_work+0x24/0x40 [imx_dsp_rproc]\n process_one_work+0x1d0/0x354\n worker_thread+0x13c/0x470\n kthread+0x154/0x160\n ret_from_fork+0x10/0x20\n\nAdd mutex protection in imx_dsp_rproc_vq_work(), if the state is\nnot running, then just skip calling rproc_vq_interrupt().\n\nAlso the flush workqueue operation can't be added in rproc stop\nfor the same reason.
