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-2022-50657 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2022-50657/ (Markdown: https://insights.sbomify.com/CVE-2022-50657/index.md)","id":"CVE-2022-50657","markdown":"https://insights.sbomify.com/CVE-2022-50657/index.md","name":"CVE-2022-50657","record":{"aliases":["DEBIAN-CVE-2022-50657","GHSA-jcqw-583m-jhjv","UBUNTU-CVE-2022-50657"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"none","summary":"Missing memory copy in RISC-V KASAN initialization causes page faults and system crashes when accessing shadow regions.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nriscv: mm: add missing memcpy in kasan_init\n\nHi Atish,\n\nIt seems that the panic is due to the missing memcpy during kasan_init.\nCould you please check whether this patch is helpful?\n\nWhen doing kasan_populate, the new allocated base_pud/base_p4d should\ncontain kasan_early_shadow_{pud, p4d}'s content.
