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-2023-53282 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-2023-53282/ (Markdown: https://insights.sbomify.com/CVE-2023-53282/index.md)","id":"CVE-2023-53282","markdown":"https://insights.sbomify.com/CVE-2023-53282/index.md","name":"CVE-2023-53282","record":{"aliases":["BELL-CVE-2023-53282","DEBIAN-CVE-2023-53282","GHSA-7wcq-h796-g66p","ROOT-OS-DEBIAN-11-CVE-2023-53282","UBUNTU-CVE-2023-53282"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel lpfc driver allows attackers to cause a denial of service or potentially execute code via sysfs firmware writes.","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":"cisa-adp","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: lpfc: Fix use-after-free KFENCE violation during sysfs firmware write\n\nDuring the sysfs firmware write process, a use-after-free read warning is\nlogged from the lpfc_wr_object() routine:\n\n  BUG: KFENCE: use-after-free read in lpfc_wr_object+0x235/0x310 [lpfc]\n  Use-after-free read at 0x0000000000cf164d (in kfence-#111):\n  lpfc_wr_object+0x235/0x310 [lpfc]\n  lpfc_write_firmware.cold+0x206/0x30d [lpfc]\n  lpfc_sli4_request_firmware_update+0xa6/0x100 [lpfc]\n  lpfc_request_firmware_upgrade_store+0x66/0xb0 [lpfc]\n  kernfs_fop_write_iter+0x121/0x1b0\n  new_sync_write+0x11c/0x1b0\n  vfs_write+0x1ef/0x280\n  ksys_write+0x5f/0xe0\n  do_syscall_64+0x59/0x90\n  entry_SYSCALL_64_after_hwframe+0x63/0xcd\n\nThe driver accessed wr_object pointer data, which was initialized into\nmailbox payload memory, after the mailbox object was released back to the\nmailbox pool.\n\nFix by moving the mailbox free calls to the end of the routine ensuring\nthat we don't reference internal mailbox memory after release.","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: lpfc: Fix use-after-free KFENCE violation during sysfs firmware write","id":"CVE-2023-53282","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2023-53283"},"packages":[],"prev":{"headline":"drivers: staging: rtl8723bs: Fix locking in _rtw_join_timeout_handler()","id":"CVE-2023-53281"},"products":["Linux"],"published":"2025-09-16","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel lpfc driver allows attackers to cause a denial of service or potentially execute code via sysfs firmware writes.","url":"https://insights.sbomify.com/CVE-2023-53282/"}
