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-2023-52978 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-2023-52978/ (Markdown: https://insights.sbomify.com/CVE-2023-52978/index.md)","id":"CVE-2023-52978","markdown":"https://insights.sbomify.com/CVE-2023-52978/index.md","name":"CVE-2023-52978","record":{"aliases":["BELL-CVE-2023-52978","DEBIAN-CVE-2023-52978","GHSA-7m9p-x22p-v2hg","UBUNTU-CVE-2023-52978"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can cause a kernel panic and system crash by placing a kprobe at an illegal instruction position on RISC-V systems.","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":"cisa-adp","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\nriscv: kprobe: Fixup kernel panic when probing an illegal position\n\nThe kernel would panic when probed for an illegal position. eg:\n\n(CONFIG_RISCV_ISA_C=n)\n\necho 'p:hello kernel_clone+0x16 a0=%a0' \u003e\u003e kprobe_events\necho 1 \u003e events/kprobes/hello/enable\ncat trace\n\nKernel panic - not syncing: stack-protector: Kernel stack\nis corrupted in: __do_sys_newfstatat+0xb8/0xb8\nCPU: 0 PID: 111 Comm: sh Not tainted\n6.2.0-rc1-00027-g2d398fe49a4d #490\nHardware name: riscv-virtio,qemu (DT)\nCall Trace:\n[\u003cffffffff80007268\u003e] dump_backtrace+0x38/0x48\n[\u003cffffffff80c5e83c\u003e] show_stack+0x50/0x68\n[\u003cffffffff80c6da28\u003e] dump_stack_lvl+0x60/0x84\n[\u003cffffffff80c6da6c\u003e] dump_stack+0x20/0x30\n[\u003cffffffff80c5ecf4\u003e] panic+0x160/0x374\n[\u003cffffffff80c6db94\u003e] generic_handle_arch_irq+0x0/0xa8\n[\u003cffffffff802deeb0\u003e] sys_newstat+0x0/0x30\n[\u003cffffffff800158c0\u003e] sys_clone+0x20/0x30\n[\u003cffffffff800039e8\u003e] ret_from_syscall+0x0/0x4\n---[ end Kernel panic - not syncing: stack-protector:\nKernel stack is corrupted in: __do_sys_newfstatat+0xb8/0xb8 ]---\n\nThat is because the kprobe's ebreak instruction broke the kernel's\noriginal code.
