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-2023-53182 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-2023-53182/ (Markdown: https://insights.sbomify.com/CVE-2023-53182/index.md)","id":"CVE-2023-53182","markdown":"https://insights.sbomify.com/CVE-2023-53182/index.md","name":"CVE-2023-53182","record":{"aliases":["BELL-CVE-2023-53182","DEBIAN-CVE-2023-53182","GHSA-5736-9cvg-p77g","UBUNTU-CVE-2023-53182"],"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 null pointer dereference in the Linux kernel's ACPICA component can cause a system crash, requiring a kernel patch.","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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nACPICA: Avoid undefined behavior: applying zero offset to null pointer\n\nACPICA commit 770653e3ba67c30a629ca7d12e352d83c2541b1e\n\nBefore this change we see the following UBSAN stack trace in Fuchsia:\n\n  #0    0x000021e4213b3302 in acpi_ds_init_aml_walk(struct acpi_walk_state*, union acpi_parse_object*, struct acpi_namespace_node*, u8*, u32, struct acpi_evaluate_info*, u8) ../../third_party/acpica/source/components/dispatcher/dswstate.c:682 \u003cplatform-bus-x86.so\u003e+0x233302\n  #1.2  0x000020d0f660777f in ubsan_get_stack_trace() compiler-rt/lib/ubsan/ubsan_diag.cpp:41 \u003clibclang_rt.asan.so\u003e+0x3d77f\n  #1.1  0x000020d0f660777f in maybe_print_stack_trace() compiler-rt/lib/ubsan/ubsan_diag.cpp:51 \u003clibclang_rt.asan.so\u003e+0x3d77f\n  #1    0x000020d0f660777f in ~scoped_report() compiler-rt/lib/ubsan/ubsan_diag.cpp:387 \u003clibclang_rt.asan.so\u003e+0x3d77f\n  #2    0x000020d0f660b96d in handlepointer_overflow_impl() compiler-rt/lib/ubsan/ubsan_handlers.cpp:809 \u003clibclang_rt.asan.so\u003e+0x4196d\n  #3    0x000020d0f660b50d in compiler-rt/lib/ubsan/ubsan_handlers.cpp:815 \u003clibclang_rt.asan.so\u003e+0x4150d\n  #4    0x000021e4213b3302 in acpi_ds_init_aml_walk(struct acpi_walk_state*, union acpi_parse_object*, struct acpi_namespace_node*, u8*, u32, struct acpi_evaluate_info*, u8) ../../third_party/acpica/source/components/dispatcher/dswstate.c:682 \u003cplatform-bus-x86.so\u003e+0x233302\n  #5    0x000021e4213e2369 in acpi_ds_call_control_method(struct acpi_thread_state*, struct acpi_walk_state*, union acpi_parse_object*) ../../third_party/acpica/source/components/dispatcher/dsmethod.c:605 \u003cplatform-bus-x86.so\u003e+0x262369\n  #6    0x000021e421437fac in acpi_ps_parse_aml(struct acpi_walk_state*) ../../third_party/acpica/source/components/parser/psparse.c:550 \u003cplatform-bus-x86.so\u003e+0x2b7fac\n  #7    0x000021e4214464d2 in acpi_ps_execute_method(struct acpi_evaluate_info*) ../../third_party/acpica/source/components/parser/psxface.c:244 \u003cplatform-bus-x86.so\u003e+0x2c64d2\n  #8    0x000021e4213aa052 in acpi_ns_evaluate(struct acpi_evaluate_info*) ../../third_party/acpica/source/components/namespace/nseval.c:250 \u003cplatform-bus-x86.so\u003e+0x22a052\n  #9    0x000021e421413dd8 in acpi_ns_init_one_device(acpi_handle, u32, void*, void**) ../../third_party/acpica/source/components/namespace/nsinit.c:735 \u003cplatform-bus-x86.so\u003e+0x293dd8\n  #10   0x000021e421429e98 in acpi_ns_walk_namespace(acpi_object_type, acpi_handle, u32, u32, acpi_walk_callback, acpi_walk_callback, void*, void**) ../../third_party/acpica/source/components/namespace/nswalk.c:298 \u003cplatform-bus-x86.so\u003e+0x2a9e98\n  #11   0x000021e4214131ac in acpi_ns_initialize_devices(u32) ../../third_party/acpica/source/components/namespace/nsinit.c:268 \u003cplatform-bus-x86.so\u003e+0x2931ac\n  #12   0x000021e42147c40d in acpi_initialize_objects(u32) ../../third_party/acpica/source/components/utilities/utxfinit.c:304 \u003cplatform-bus-x86.so\u003e+0x2fc40d\n  #13   0x000021e42126d603 in acpi::acpi_impl::initialize_acpi(acpi::acpi_impl*) ../../src/devices/board/lib/acpi/acpi-impl.cc:224 \u003cplatform-bus-x86.so\u003e+0xed603\n\nAdd a simple check that avoids incrementing a pointer by zero, but\notherwise behaves as before.
