The sibling converters\np54_convert_output_limits() and p54_convert_db() already validate\ntheir counts against the entry length; this path was missed.\n\nReject the entry when the counts do not fit in the entry data.","modified":"2026-10-08T02:52:53.424441851Z","published":"2026-10-06T08:44:30.096Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98188.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/03d313e3dfb49a44c10a5c423452967694fb85e2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3bdcc4d61212b001b8752d80036509b4974ce16c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/41cdf14bf4b52fbe4673a172c2a6ad756cb08111"},{"type":"WEB","url":"https://git.kernel.org/stable/c/42f4b03971f9d6329c4cbd1ea5155210d16ab65b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4d767d6f8753db22bfc14c2724bd9cee677ffb03"},{"type":"WEB","url":"https://git.kernel.org/stable/c/81084c967c18233b19799a0c3352ebac043f31e2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b0c906107150b16925ee66da09127259864c7f36"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ce858fa6b8a214dee5adb82358885fa024cdd887"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98188.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98188"},{"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":"eff1a59c48e3c6a006eb4fe5f2e405a996f2259d"},{"fixed":"81084c967c18233b19799a0c3352ebac043f31e2"},{"fixed":"41cdf14bf4b52fbe4673a172c2a6ad756cb08111"},{"fixed":"03d313e3dfb49a44c10a5c423452967694fb85e2"},{"fixed":"42f4b03971f9d6329c4cbd1ea5155210d16ab65b"},{"fixed":"4d767d6f8753db22bfc14c2724bd9cee677ffb03"},{"fixed":"3bdcc4d61212b001b8752d80036509b4974ce16c"},{"fixed":"b0c906107150b16925ee66da09127259864c7f36"},{"fixed":"ce858fa6b8a214dee5adb82358885fa024cdd887"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98188.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.24"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98188.json"}}],"schema_version":"1.9.0"}
