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-2026-23078 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-2026-23078/ (Markdown: https://insights.sbomify.com/CVE-2026-23078/index.md)","id":"CVE-2026-23078","markdown":"https://insights.sbomify.com/CVE-2026-23078/index.md","name":"CVE-2026-23078","record":{"aliases":["AZL-77208","BELL-CVE-2026-23078","DEBIAN-CVE-2026-23078","GHSA-25gw-4v5m-94pp","ROOT-OS-DEBIAN-12-CVE-2026-23078","ROOT-OS-DEBIAN-13-CVE-2026-23078","ROOT-OS-UBUNTU-2204-CVE-2026-23078","ROOT-OS-UBUNTU-2404-CVE-2026-23078","UBUNTU-CVE-2026-23078"],"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":"low_privilege","summary":"A buffer overflow in the Linux kernel's Scarlett2 audio driver allows local attackers to execute arbitrary code or escalate privileges.","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":7.8,"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\nALSA: scarlett2: Fix buffer overflow in config retrieval\n\nThe scarlett2_usb_get_config() function has a logic error in the\nendianness conversion code that can cause buffer overflows when\ncount \u003e 1.\n\nThe code checks `if (size == 2)` where `size` is the total buffer size in\nbytes, then loops `count` times treating each element as u16 (2 bytes).\nThis causes the loop to access `count * 2` bytes when the buffer only\nhas `size` bytes allocated.\n\nFix by checking the element size (config_item-\u003esize) instead of the\ntotal buffer size.
