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-2025-40358 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-2025-40358/ (Markdown: https://insights.sbomify.com/CVE-2025-40358/index.md)","id":"CVE-2025-40358","markdown":"https://insights.sbomify.com/CVE-2025-40358/index.md","name":"CVE-2025-40358","record":{"aliases":["BELL-CVE-2025-40358","DEBIAN-CVE-2025-40358","GHSA-qchg-c772-c4pf","ROOT-OS-DEBIAN-11-CVE-2025-40358","ROOT-OS-DEBIAN-12-CVE-2025-40358","ROOT-OS-DEBIAN-13-CVE-2025-40358","ROOT-OS-UBUNTU-2204-CVE-2025-40358","ROOT-OS-UBUNTU-2404-CVE-2025-40358","UBUNTU-CVE-2025-40358"],"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 kernel bug causes false-positive KASAN out-of-bounds reports when unwinding non-current task stacks, potentially leading to system crashes or instability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nriscv: stacktrace: Disable KASAN checks for non-current tasks\n\nUnwinding the stack of a task other than current, KASAN would report\n\"BUG: KASAN: out-of-bounds in walk_stackframe+0x41c/0x460\"\n\nThere is a same issue on x86 and has been resolved by the commit\n84936118bdf3 (\"x86/unwind: Disable KASAN checks for non-current tasks\")\nThe solution could be applied to RISC-V too.\n\nThis patch also can solve the issue:\nhttps://seclists.org/oss-sec/2025/q4/23\n\n[pjw@kernel.org: clean up checkpatch issues]","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"riscv: stacktrace: Disable KASAN checks for non-current tasks","id":"CVE-2025-40358","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"perf/x86/intel: Fix KASAN global-out-of-bounds warning","id":"CVE-2025-40359"},"packages":[],"prev":{"headline":"net/smc: fix general protection fault in __smc_diag_dump","id":"CVE-2025-40357"},"products":["Linux"],"published":"2025-12-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A kernel bug causes false-positive KASAN out-of-bounds reports when unwinding non-current task stacks, potentially leading to system crashes or instability.","url":"https://insights.sbomify.com/CVE-2025-40358/"}
