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-2023-53803 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-2023-53803/ (Markdown: https://insights.sbomify.com/CVE-2023-53803/index.md)","id":"CVE-2023-53803","markdown":"https://insights.sbomify.com/CVE-2023-53803/index.md","name":"CVE-2023-53803","record":{"aliases":["BELL-CVE-2023-53803","DEBIAN-CVE-2023-53803","GHSA-7mw7-q5qp-mcqq","UBUNTU-CVE-2023-53803"],"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":"none","summary":"A slab-out-of-bounds read in the Linux kernel SES driver can cause a system crash, requiring a kernel patch to prevent denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/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\nscsi: ses: Fix slab-out-of-bounds in ses_enclosure_data_process()\n\nA fix for:\n\nBUG: KASAN: slab-out-of-bounds in ses_enclosure_data_process+0x949/0xe30 [ses]\nRead of size 1 at addr ffff88a1b043a451 by task systemd-udevd/3271\n\nChecking after (and before in next loop) addl_desc_ptr[1] is sufficient, we\nexpect the size to be sanitized before first access to addl_desc_ptr[1].\nMake sure we don't walk beyond end of page.","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":"scsi: ses: Fix slab-out-of-bounds in ses_enclosure_data_process()","id":"CVE-2023-53803","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":8,"next":{"headline":"nilfs2: fix use-after-free bug of nilfs_root in nilfs_evict_inode()","id":"CVE-2023-53804"},"packages":[],"prev":{"headline":"wifi: ath9k: htc_hst: free skb in ath9k_htc_rx_msg() if there is no callback function","id":"CVE-2023-53802"},"products":["Linux"],"published":"2025-12-09","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A slab-out-of-bounds read in the Linux kernel SES driver can cause a system crash, requiring a kernel patch to prevent denial of service.","url":"https://insights.sbomify.com/CVE-2023-53803/"}
