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-2023-52975 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-2023-52975/ (Markdown: https://insights.sbomify.com/CVE-2023-52975/index.md)","id":"CVE-2023-52975","markdown":"https://insights.sbomify.com/CVE-2023-52975/index.md","name":"CVE-2023-52975","record":{"aliases":["BELL-CVE-2023-52975","DEBIAN-CVE-2023-52975","GHSA-vm8w-gf89-48f9","ROOT-OS-DEBIAN-11-CVE-2023-52975","UBUNTU-CVE-2023-52975"],"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 use-after-free vulnerability in the Linux kernel iSCSI TCP module allows a local attacker to cause a system crash during session logout.","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":"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\nscsi: iscsi_tcp: Fix UAF during logout when accessing the shost ipaddress\n\nBug report and analysis from Ding Hui.\n\nDuring iSCSI session logout, if another task accesses the shost ipaddress\nattr, we can get a KASAN UAF report like this:\n\n[  276.942144] BUG: KASAN: use-after-free in _raw_spin_lock_bh+0x78/0xe0\n[  276.942535] Write of size 4 at addr ffff8881053b45b8 by task cat/4088\n[  276.943511] CPU: 2 PID: 4088 Comm: cat Tainted: G            E      6.1.0-rc8+ #3\n[  276.943997] Hardware name: VMware, Inc.
