It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-54132 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-2023-54132/ (Markdown: https://insights.sbomify.com/CVE-2023-54132/index.md)","id":"CVE-2023-54132","markdown":"https://insights.sbomify.com/CVE-2023-54132/index.md","name":"CVE-2023-54132","record":{"aliases":["BELL-CVE-2023-54132","DEBIAN-CVE-2023-54132","GHSA-6m52-8r59-r63x","UBUNTU-CVE-2023-54132"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel EROFS","requires_auth":"none","summary":"A crafted EROFS image with an invalid clusterofs value causes a kernel page fault and crash, leading to denial of service.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nerofs: stop parsing non-compact HEAD index if clusterofs is invalid\n\nSyzbot generated a crafted image [1] with a non-compact HEAD index of\nclusterofs 33024 while valid numbers should be 0 ~ lclustersize-1,\nwhich causes the following unexpected behavior as below:\n\n BUG: unable to handle page fault for address: fffff52101a3fff9\n #PF: supervisor read access in kernel mode\n #PF: error_code(0x0000) - not-present page\n PGD 23ffed067 P4D 23ffed067 PUD 0\n Oops: 0000 [#1] PREEMPT SMP KASAN\n CPU: 1 PID: 4398 Comm: kworker/u5:1 Not tainted 6.3.0-rc6-syzkaller-g09a9639e56c0 #0\n Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 03/30/2023\n Workqueue: erofs_worker z_erofs_decompressqueue_work\n RIP: 0010:z_erofs_decompress_queue+0xb7e/0x2b40\n ...\n Call Trace:\n  \u003cTASK\u003e\n  z_erofs_decompressqueue_work+0x99/0xe0\n  process_one_work+0x8f6/0x1170\n  worker_thread+0xa63/0x1210\n  kthread+0x270/0x300\n  ret_from_fork+0x1f/0x30\n\nNote that normal images or images using compact indexes are not\nimpacted.
