{"id":"CVE-2026-90137","summary":"platform/x86: hp-bioscfg: fix password encoding bounds check","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: hp-bioscfg: fix password encoding bounds check\n\nThe password PSWD_ENCODINGS parser reads password_obj[elem + pos_values]\nwhile copying the supported password encodings from the ACPI package.\n\nThe outer loop only guarantees that elem is within password_obj_count.\nThe encoding count is bounded by MAX_ENCODINGS_SIZE, but that does not\nguarantee that the ACPI package contains enough entries for all\nelem + pos_values accesses.\n\nA malformed package can therefore declare a non-zero encoding count\nwithout providing enough string objects, causing the parser to read past\nthe ACPI package array and pass an out-of-bounds string pointer and\nlength to hp_convert_hexstr_to_str().\n\nAdd the same computed-index bounds check used by the other offset-based\npackage parsing loops before reading password_obj[elem + pos_values].","modified":"2026-09-19T03:47:24.745937378Z","published":"2026-09-17T16:06:35.829Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90137.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/59fe8491ddaa03a510b352552e6ee291e7ce45d3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a7499b8fd34438c1b11964e0e7ef5bd590fec92"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ace1ba5fca0ab775b3641e154bcbc3ccde26a71a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c224759555a13735b0d67561d818cefe00c3309a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e213939ed9e6e6badf7aa48c4c8dd9a9cdf00615"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90137.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90137"},{"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":"8646a3b5ee3a5b384a22a721f37c24274d974045"},{"fixed":"c224759555a13735b0d67561d818cefe00c3309a"},{"fixed":"59fe8491ddaa03a510b352552e6ee291e7ce45d3"},{"fixed":"ace1ba5fca0ab775b3641e154bcbc3ccde26a71a"},{"fixed":"8a7499b8fd34438c1b11964e0e7ef5bd590fec92"},{"fixed":"e213939ed9e6e6badf7aa48c4c8dd9a9cdf00615"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90137.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90137.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
