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-2023-53613 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-2023-53613/ (Markdown: https://insights.sbomify.com/CVE-2023-53613/index.md)","id":"CVE-2023-53613","markdown":"https://insights.sbomify.com/CVE-2023-53613/index.md","name":"CVE-2023-53613","record":{"aliases":["BELL-CVE-2023-53613","DEBIAN-CVE-2023-53613","GHSA-6789-c3xj-p7cq","UBUNTU-CVE-2023-53613"],"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 use-after-free in the Linux kernel DAX subsystem can cause a system crash when removing a device-dax region provider under specific debug configurations.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndax: Fix dax_mapping_release() use after free\n\nA CONFIG_DEBUG_KOBJECT_RELEASE test of removing a device-dax region\nprovider (like modprobe -r dax_hmem) yields:\n\n kobject: 'mapping0' (ffff93eb460e8800): kobject_release, parent 0000000000000000 (delayed 2000)\n [..]\n DEBUG_LOCKS_WARN_ON(1)\n WARNING: CPU: 23 PID: 282 at kernel/locking/lockdep.c:232 __lock_acquire+0x9fc/0x2260\n [..]\n RIP: 0010:__lock_acquire+0x9fc/0x2260\n [..]\n Call Trace:\n  \u003cTASK\u003e\n [..]\n  lock_acquire+0xd4/0x2c0\n  ? ida_free+0x62/0x130\n  _raw_spin_lock_irqsave+0x47/0x70\n  ? ida_free+0x62/0x130\n  ida_free+0x62/0x130\n  dax_mapping_release+0x1f/0x30\n  device_release+0x36/0x90\n  kobject_delayed_cleanup+0x46/0x150\n\nDue to attempting ida_free() on an ida object that has already been\nfreed.
