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-2025-68783 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-2025-68783/ (Markdown: https://insights.sbomify.com/CVE-2025-68783/index.md)","id":"CVE-2025-68783","markdown":"https://insights.sbomify.com/CVE-2025-68783/index.md","name":"CVE-2025-68783","record":{"aliases":["AZL-74372","BELL-CVE-2025-68783","DEBIAN-CVE-2025-68783","GHSA-8vvr-5pch-2fhg","ROOT-OS-DEBIAN-11-CVE-2025-68783","ROOT-OS-DEBIAN-12-CVE-2025-68783","ROOT-OS-DEBIAN-13-CVE-2025-68783","ROOT-OS-UBUNTU-2204-CVE-2025-68783","ROOT-OS-UBUNTU-2404-CVE-2025-68783","UBUNTU-CVE-2025-68783"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A missing bounds check in the Linux kernel USB mixer driver allows out-of-bounds writes, potentially enabling local privilege escalation or code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nALSA: usb-mixer: us16x08: validate meter packet indices\n\nget_meter_levels_from_urb() parses the 64-byte meter packets sent by\nthe device and fills the per-channel arrays meter_level[],\ncomp_level[] and master_level[] in struct snd_us16x08_meter_store.\n\nCurrently the function derives the channel index directly from the\nmeter packet (MUB2(meter_urb, s) - 1) and uses it to index those\narrays without validating the range.
