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-2023-52559 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-2023-52559/ (Markdown: https://insights.sbomify.com/CVE-2023-52559/index.md)","id":"CVE-2023-52559","markdown":"https://insights.sbomify.com/CVE-2023-52559/index.md","name":"CVE-2023-52559","record":{"aliases":["BELL-CVE-2023-52559","DEBIAN-CVE-2023-52559","GHSA-94pf-4p5q-jc3r","UBUNTU-CVE-2023-52559"],"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":"A local attacker can trigger intermittent suspend or hibernation failures in the Linux kernel by exploiting improper memory allocation handling in the IOMMU suspend callback.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\niommu/vt-d: Avoid memory allocation in iommu_suspend()\n\nThe iommu_suspend() syscore suspend callback is invoked with IRQ disabled.\nAllocating memory with the GFP_KERNEL flag may re-enable IRQs during\nthe suspend callback, which can cause intermittent suspend/hibernation\nproblems with the following kernel traces:\n\nCalling iommu_suspend+0x0/0x1d0\n------------[ cut here ]------------\nWARNING: CPU: 0 PID: 15 at kernel/time/timekeeping.c:868 ktime_get+0x9b/0xb0\n...\nCPU: 0 PID: 15 Comm: rcu_preempt Tainted: G     U      E      6.3-intel #r1\nRIP: 0010:ktime_get+0x9b/0xb0\n...\nCall Trace:\n \u003cIRQ\u003e\n tick_sched_timer+0x22/0x90\n ?
