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-2024-50175 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-2024-50175/ (Markdown: https://insights.sbomify.com/CVE-2024-50175/index.md)","id":"CVE-2024-50175","markdown":"https://insights.sbomify.com/CVE-2024-50175/index.md","name":"CVE-2024-50175","record":{"aliases":["BELL-CVE-2024-50175","DEBIAN-CVE-2024-50175","GHSA-8pr8-xc5p-c8gp","UBUNTU-CVE-2024-50175"],"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 logic error in the Qualcomm CAMSS driver causes a kernel warning and prevents restarting the camera stream, leading to a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: qcom: camss: Remove use_count guard in stop_streaming\n\nThe use_count check was introduced so that multiple concurrent Raw Data\nInterfaces RDIs could be driven by different virtual channels VCs on the\nCSIPHY input driving the video pipeline.\n\nThis is an invalid use of use_count though as use_count pertains to the\nnumber of times a video entity has been opened by user-space not the number\nof active streams.\n\nIf use_count and stream-on count don't agree then stop_streaming() will\nbreak as is currently the case and has become apparent when using CAMSS\nwith libcamera's released softisp 0.3.\n\nThe use of use_count like this is a bit hacky and right now breaks regular\nusage of CAMSS for a single stream case.
