{"id":"CVE-2026-89497","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-89497","summary":"orangefs: skip leading spaces before parsing client debug masks","details":"In the Linux kernel, the following vulnerability has been resolved:\n\norangefs: skip leading spaces before parsing client debug masks\n\norangefs_prepare_cdm_array() sizes each client debug keyword buffer\nwith strcspn(cds_head, \" \"), but then parses the keyword with %s. The\n%s conversion skips leading whitespace, while strcspn() does not.\n\nIf a client debug entry starts with a space, the allocation can be sized\nfor an empty keyword while sscanf() copies the following non-empty token.\nThis can write past the end of the allocated keyword buffer.\n\nSkip leading spaces before computing the keyword length so the allocation\nmatches the string parsed by sscanf().","published":"2026-09-11T19:43:47.439Z","modified":"2026-09-14T03:46:06.003741514Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.12.109"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/116d14f29a0524853c9316f32a2ac06cff5d4bf6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/15d79c806231e62a7b746d3b42626810004e1b27"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1774c5b3713add32fe15ab0d3db4b73355f94e35"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d410cd5303ec59c7cf23dd61423752ce8e9ecb59"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89497.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89497"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-14T03:46:06.003741514Z"}}
