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-2022-50206 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-2022-50206/ (Markdown: https://insights.sbomify.com/CVE-2022-50206/index.md)","id":"CVE-2022-50206","markdown":"https://insights.sbomify.com/CVE-2022-50206/index.md","name":"CVE-2022-50206","record":{"aliases":["DEBIAN-CVE-2022-50206","GHSA-qgp7-v6fq-jxvw","UBUNTU-CVE-2022-50206"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel arm64 emulation sysctl handler causes a null pointer dereference, leading to a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"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":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\narm64: fix oops in concurrently setting insn_emulation sysctls\n\nemulation_proc_handler() changes table-\u003edata for proc_dointvec_minmax\nand can generate the following Oops if called concurrently with itself:\n\n | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010\n | Internal error: Oops: 96000006 [#1] SMP\n | Call trace:\n | update_insn_emulation_mode+0xc0/0x148\n | emulation_proc_handler+0x64/0xb8\n | proc_sys_call_handler+0x9c/0xf8\n | proc_sys_write+0x18/0x20\n | __vfs_write+0x20/0x48\n | vfs_write+0xe4/0x1d0\n | ksys_write+0x70/0xf8\n | __arm64_sys_write+0x20/0x28\n | el0_svc_common.constprop.0+0x7c/0x1c0\n | el0_svc_handler+0x2c/0xa0\n | el0_svc+0x8/0x200\n\nTo fix this issue, keep the table-\u003edata as \u0026insn-\u003ecurrent_mode and\nuse container_of() to retrieve the insn pointer.
