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-2023-54007 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-2023-54007/ (Markdown: https://insights.sbomify.com/CVE-2023-54007/index.md)","id":"CVE-2023-54007","markdown":"https://insights.sbomify.com/CVE-2023-54007/index.md","name":"CVE-2023-54007","record":{"aliases":["BELL-CVE-2023-54007","DEBIAN-CVE-2023-54007","GHSA-j5xc-fjvv-7rjx","UBUNTU-CVE-2023-54007"],"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 race condition in the Linux kernel's vmci_host_poll function allows a local attacker to cause a general protection fault and system crash.","user_interaction":"not_required","vuln_class":"race_condition"},"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\nvmci_host: fix a race condition in vmci_host_poll() causing GPF\n\nDuring fuzzing, a general protection fault is observed in\nvmci_host_poll().\n\ngeneral protection fault, probably for non-canonical address 0xdffffc0000000019: 0000 [#1] PREEMPT SMP KASAN\nKASAN: null-ptr-deref in range [0x00000000000000c8-0x00000000000000cf]\nRIP: 0010:__lock_acquire+0xf3/0x5e00 kernel/locking/lockdep.c:4926\n\u003c- omitting registers -\u003e\nCall Trace:\n \u003cTASK\u003e\n lock_acquire+0x1a4/0x4a0 kernel/locking/lockdep.c:5672\n __raw_spin_lock_irqsave include/linux/spinlock_api_smp.h:110 [inline]\n _raw_spin_lock_irqsave+0xb3/0x100 kernel/locking/spinlock.c:162\n add_wait_queue+0x3d/0x260 kernel/sched/wait.c:22\n poll_wait include/linux/poll.h:49 [inline]\n vmci_host_poll+0xf8/0x2b0 drivers/misc/vmw_vmci/vmci_host.c:174\n vfs_poll include/linux/poll.h:88 [inline]\n do_pollfd fs/select.c:873 [inline]\n do_poll fs/select.c:921 [inline]\n do_sys_poll+0xc7c/0x1aa0 fs/select.c:1015\n __do_sys_ppoll fs/select.c:1121 [inline]\n __se_sys_ppoll+0x2cc/0x330 fs/select.c:1101\n do_syscall_x64 arch/x86/entry/common.c:51 [inline]\n do_syscall_64+0x4e/0xa0 arch/x86/entry/common.c:82\n entry_SYSCALL_64_after_hwframe+0x46/0xb0\n\nExample thread interleaving that causes the general protection fault\nis as follows:\n\nCPU1 (vmci_host_poll)               CPU2 (vmci_host_do_init_context)\n-----                               -----\n// Read uninitialized context\ncontext = vmci_host_dev-\u003econtext;\n                                    // Initialize context\n                                    vmci_host_dev-\u003econtext = vmci_ctx_create();\n                                    vmci_host_dev-\u003ect_type = VMCIOBJ_CONTEXT;\n\nif (vmci_host_dev-\u003ect_type == VMCIOBJ_CONTEXT) {\n    // Dereferencing the wrong pointer\n    poll_wait(..., \u0026context-\u003ehost_context);\n}\n\nIn this scenario, vmci_host_poll() reads vmci_host_dev-\u003econtext first,\nand then reads vmci_host_dev-\u003ect_type to check that\nvmci_host_dev-\u003econtext is initialized.
