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-2022-50239 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-2022-50239/ (Markdown: https://insights.sbomify.com/CVE-2022-50239/index.md)","id":"CVE-2022-50239","markdown":"https://insights.sbomify.com/CVE-2022-50239/index.md","name":"CVE-2022-50239","record":{"aliases":["DEBIAN-CVE-2022-50239","GHSA-gvp8-gmj5-m6g2","UBUNTU-CVE-2022-50239"],"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 kernel oops occurs when the Qualcomm cpufreq driver attempts to write to a read-only memory region, causing a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncpufreq: qcom: fix writes in read-only memory region\n\nThis commit fixes a kernel oops because of a write in some read-only memory:\n\n\t[    9.068287] Unable to handle kernel write to read-only memory at virtual address ffff800009240ad8\n\t..snip..\n\t[    9.138790] Internal error: Oops: 9600004f [#1] PREEMPT SMP\n\t..snip..\n\t[    9.269161] Call trace:\n\t[    9.276271]  __memcpy+0x5c/0x230\n\t[    9.278531]  snprintf+0x58/0x80\n\t[    9.282002]  qcom_cpufreq_msm8939_name_version+0xb4/0x190\n\t[    9.284869]  qcom_cpufreq_probe+0xc8/0x39c\n\t..snip..\n\nThe following line defines a pointer that point to a char buffer stored\nin read-only memory:\n\n\tchar *pvs_name = \"speedXX-pvsXX-vXX\";\n\nThis pointer is meant to hold a template \"speedXX-pvsXX-vXX\" where the\nXX values get overridden by the qcom_cpufreq_krait_name_version function.
