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-2026-74514 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-2026-74514/ (Markdown: https://insights.sbomify.com/CVE-2026-74514/index.md)","id":"CVE-2026-74514","markdown":"https://insights.sbomify.com/CVE-2026-74514/index.md","name":"CVE-2026-74514","record":{"aliases":["BELL-CVE-2026-74514","DEBIAN-CVE-2026-74514","GHSA-rw3p-g3wm-qv8p","UBUNTU-CVE-2026-74514"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel KVM","requires_auth":"low_privilege","summary":"A reference counting error in KVM s390 PCI memory accounting allows local attackers to cause memory corruption, potentially leading to privilege escalation or denial of service.","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\nKVM: s390: pci: Fix memory accounting for pinned/unpinned pages\n\nThe account_mem() and unaccount_mem() functions call get_uid() which\nincrements the reference count of struct user_struct on every invocation.\nBut we don't decrement the count by calling free_uid().
