{"id":"CVE-2026-89444","summary":"platform/x86: dell-wmi-sysman: Don't hex dump attribute security buffer","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: dell-wmi-sysman: Don't hex dump attribute security buffer\n\nset_attribute() populates the security area of the BIOS attribute request\nbuffer with the current admin password via populate_security_buffer(), then\ndumps the whole request buffer with print_hex_dump_bytes(). This can expose\nthe plaintext admin password in the kernel log.\n\nThe same issue was fixed for the password attribute path by\ncommit d1a196e0a6dc (\"platform/x86: dell-wmi-sysman: Don't hex dump\nplaintext password data\"). Remove the remaining dump from the BIOS\nattribute path.","modified":"2026-09-13T03:47:18.187235327Z","published":"2026-09-11T19:43:12.076Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89444.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/22222f92b0a5116eb4aac4be81e7b770adfa32ee"},{"type":"WEB","url":"https://git.kernel.org/stable/c/83c80495e45eddf64c6525fb582d8db68f256b71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ceeee18c927958b74a04b92cf084fc496fa21e8b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eb73b9d51490bec4f73ac6efdba5ac535fcfee74"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89444.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89444"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e8a60aa7404bfef37705da5607c97737073ac38d"},{"fixed":"ceeee18c927958b74a04b92cf084fc496fa21e8b"},{"fixed":"22222f92b0a5116eb4aac4be81e7b770adfa32ee"},{"fixed":"eb73b9d51490bec4f73ac6efdba5ac535fcfee74"},{"fixed":"83c80495e45eddf64c6525fb582d8db68f256b71"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89444.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"6.12.109"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89444.json"}}],"schema_version":"1.9.0"}
