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-2023-54291 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-2023-54291/ (Markdown: https://insights.sbomify.com/CVE-2023-54291/index.md)","id":"CVE-2023-54291","markdown":"https://insights.sbomify.com/CVE-2023-54291/index.md","name":"CVE-2023-54291","record":{"aliases":["BELL-CVE-2023-54291","GHSA-8w34-jjgr-cq87","UBUNTU-CVE-2023-54291"],"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 cause a kernel crash by deleting a vduse device, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nvduse: fix NULL pointer dereference\n\nvduse_vdpa_set_vq_affinity callback can be called\nwith NULL value as cpu_mask when deleting the vduse\ndevice.\n\nThis patch resets virtqueue's IRQ affinity mask value\nto set all CPUs instead of dereferencing NULL cpu_mask.\n\n[ 4760.952149] BUG: kernel NULL pointer dereference, address: 0000000000000000\n[ 4760.959110] #PF: supervisor read access in kernel mode\n[ 4760.964247] #PF: error_code(0x0000) - not-present page\n[ 4760.969385] PGD 0 P4D 0\n[ 4760.971927] Oops: 0000 [#1] PREEMPT SMP PTI\n[ 4760.976112] CPU: 13 PID: 2346 Comm: vdpa Not tainted 6.4.0-rc6+ #4\n[ 4760.982291] Hardware name: Dell Inc.
