{"id":"CVE-2026-90137","aliases":[],"url":"https://o3.security/vulnerability/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].","published":"2026-09-17T16:06:35.829Z","modified":"2026-09-19T03:47:24.745937378Z","cvss":{"score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.6.157"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-19T03:47:24.745937378Z"}}
