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-2023-52752 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2023-52752/ (Markdown: https://insights.sbomify.com/CVE-2023-52752/index.md)","id":"CVE-2023-52752","markdown":"https://insights.sbomify.com/CVE-2023-52752/index.md","name":"CVE-2023-52752","record":{"aliases":["AZL-42208","BELL-CVE-2023-52752","DEBIAN-CVE-2023-52752","GHSA-c3wm-p2jr-8f5g","SUSE-SU-2024:3764-1","SUSE-SU-2024:3775-1","SUSE-SU-2024:3885-1","UBUNTU-CVE-2023-52752"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel CIFS client","requires_auth":"low_privilege","summary":"A use-after-free bug in the Linux kernel CIFS client allows a local attacker to cause a system crash by reading debug data during session teardown.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","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\nsmb: client: fix use-after-free bug in cifs_debug_data_proc_show()\n\nSkip SMB sessions that are being teared down\n(e.g. @ses-\u003eses_status == SES_EXITING) in cifs_debug_data_proc_show()\nto avoid use-after-free in @ses.\n\nThis fixes the following GPF when reading from /proc/fs/cifs/DebugData\nwhile mounting and umounting\n\n  [ 816.251274] general protection fault, probably for non-canonical\n  address 0x6b6b6b6b6b6b6d81: 0000 [#1] PREEMPT SMP NOPTI\n  ...\n  [  816.260138] Call Trace:\n  [  816.260329]  \u003cTASK\u003e\n  [  816.260499]  ?
