{"id":"CVE-2026-23131","summary":"platform/x86: hp-bioscfg: Fix kobject warnings for empty attribute names","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: hp-bioscfg: Fix kobject warnings for empty attribute names\n\nThe hp-bioscfg driver attempts to register kobjects with empty names when\nthe HP BIOS returns attributes with empty name strings. This causes\nmultiple kernel warnings:\n\n  kobject: (00000000135fb5e6): attempted to be registered with empty name!\n  WARNING: CPU: 14 PID: 3336 at lib/kobject.c:219 kobject_add_internal+0x2eb/0x310\n\nAdd validation in hp_init_bios_buffer_attribute() to check if the\nattribute name is empty after parsing it from the WMI buffer. If empty,\nlog a debug message and skip registration of that attribute, allowing the\nmodule to continue processing other valid attributes.","modified":"2026-04-02T17:30:11.427741610Z","published":"2026-02-14T15:09:58.916Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23131.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/29917c80aa96a25cbcf5876fd774a1cfd72b01a9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6476be59b7162b891b7bddbd0c2924d87379ef6c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/800b2767905d6b409b8bbe357121970f0b489a89"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fdee1b09721605f532352628d0a24623e7062efb"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23131.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23131"},{"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":"a34fc329b1895fc8a6eb12099adc47009421ba6a"},{"fixed":"29917c80aa96a25cbcf5876fd774a1cfd72b01a9"},{"fixed":"6476be59b7162b891b7bddbd0c2924d87379ef6c"},{"fixed":"800b2767905d6b409b8bbe357121970f0b489a89"},{"fixed":"fdee1b09721605f532352628d0a24623e7062efb"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23131.json"}}],"schema_version":"1.7.5"}
