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-2024-45005 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-2024-45005/ (Markdown: https://insights.sbomify.com/CVE-2024-45005/index.md)","id":"CVE-2024-45005","markdown":"https://insights.sbomify.com/CVE-2024-45005/index.md","name":"CVE-2024-45005","record":{"aliases":["BELL-CVE-2024-45005","DEBIAN-CVE-2024-45005","GHSA-cj8h-mjwg-43cc","UBUNTU-CVE-2024-45005"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel KVM","requires_auth":"low_privilege","summary":"A null pointer dereference in KVM s390 when GISA is disabled causes a host kernel crash, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","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-908","name":"Use of Uninitialized Resource"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: s390: fix validity interception issue when gisa is switched off\n\nWe might run into a SIE validity if gisa has been disabled either via using\nkernel parameter \"kvm.use_gisa=0\" or by setting the related sysfs\nattribute to N (echo N \u003e/sys/module/kvm/parameters/use_gisa).\n\nThe validity is caused by an invalid value in the SIE control block's\ngisa designation. That happens because we pass the uninitialized gisa\norigin to virt_to_phys() before writing it to the gisa designation.\n\nTo fix this we return 0 in kvm_s390_get_gisa_desc() if the origin is 0.\nkvm_s390_get_gisa_desc() is used to determine which gisa designation to\nset in the SIE control block. A value of 0 in the gisa designation disables\ngisa usage.\n\nThe issue surfaces in the host kernel with the following kernel message as\nsoon a new kvm guest start is attemted.\n\nkvm: unhandled
