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-2024-50177 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-2024-50177/ (Markdown: https://insights.sbomify.com/CVE-2024-50177/index.md)","id":"CVE-2024-50177","markdown":"https://insights.sbomify.com/CVE-2024-50177/index.md","name":"CVE-2024-50177","record":{"aliases":["AZL-54066","AZL-54068","BELL-CVE-2024-50177","DEBIAN-CVE-2024-50177","GHSA-jqx7-c9rv-mhxh","UBUNTU-CVE-2024-50177"],"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":"An integer overflow in the AMD display driver causes a UBSAN warning and potential system instability when programming phantom pipes.","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":5.5,"severity":"medium","source":"cisa-adp","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-190","name":"Integer Overflow or Wraparound"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: fix a UBSAN warning in DML2.1\n\nWhen programming phantom pipe, since cursor_width is explicity set to 0,\nthis causes calculation logic to trigger overflow for an unsigned int\ntriggering the kernel's UBSAN check as below:\n\n[   40.962845] UBSAN: shift-out-of-bounds in /tmp/amd.EfpumTkO/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:3312:34\n[   40.962849] shift exponent 4294967170 is too large for 32-bit type 'unsigned int'\n[   40.962852] CPU: 1 PID: 1670 Comm: gnome-shell Tainted: G        W  OE      6.5.0-41-generic #41~22.04.2-Ubuntu\n[   40.962854] Hardware name: Gigabyte Technology Co., Ltd.
