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-2023-52764 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-2023-52764/ (Markdown: https://insights.sbomify.com/CVE-2023-52764/index.md)","id":"CVE-2023-52764","markdown":"https://insights.sbomify.com/CVE-2023-52764/index.md","name":"CVE-2023-52764","record":{"aliases":["BELL-CVE-2023-52764","DEBIAN-CVE-2023-52764","GHSA-3f2p-fcxq-w4cm","UBUNTU-CVE-2023-52764"],"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 shift-out-of-bounds error in the Linux kernel's gspca cpia1 driver can cause a denial of service when processing invalid exposure gain values.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: gspca: cpia1: shift-out-of-bounds in set_flicker\n\nSyzkaller reported the following issue:\nUBSAN: shift-out-of-bounds in drivers/media/usb/gspca/cpia1.c:1031:27\nshift exponent 245 is too large for 32-bit type 'int'\n\nWhen the value of the variable \"sd-\u003eparams.exposure.gain\" exceeds the\nnumber of bits in an integer, a shift-out-of-bounds error is reported.
