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-2023-53561 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-2023-53561/ (Markdown: https://insights.sbomify.com/CVE-2023-53561/index.md)","id":"CVE-2023-53561","markdown":"https://insights.sbomify.com/CVE-2023-53561/index.md","name":"CVE-2023-53561","record":{"aliases":["AZL-77435","BELL-CVE-2023-53561","DEBIAN-CVE-2023-53561","GHSA-44pm-q7mw-v83g","ROOT-OS-UBUNTU-2204-CVE-2023-53561","UBUNTU-CVE-2023-53561"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WWAN driver","requires_auth":"low_privilege","summary":"A NULL pointer dereference in the Linux kernel WWAN driver can cause a system crash during device removal or suspend/resume cycles.","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\nnet: wwan: iosm: fix NULL pointer dereference when removing device\n\nIn suspend and resume cycle, the removal and rescan of device ends\nup in NULL pointer dereference.\n\nDuring driver initialization, if the ipc_imem_wwan_channel_init()\nfails to get the valid device capabilities it returns an error and\nfurther no resource (wwan struct) will be allocated.
