{"id":"CVE-2026-98833","summary":"mtd: core: call _get_device() with the master MTD","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: core: call _get_device() with the master MTD\n\n__get_mtd_device() calls the master's _get_device() callback with mtd,\nwhich may be a partition. __put_mtd_device() passes the master.\n\nThis breaks gluebi partitions because gluebi_get_device() uses\ncontainer_of() and therefore requires the master MTD. Pass the master\nto _get_device(), matching _put_device().","modified":"2026-10-20T02:30:36.544583341Z","published":"2026-10-18T15:49:42.181Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98833.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/12b31d1acd20b3185bb5f0748db0cf6874c8e9d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/95c8f36293c22d450c371167ad4f9a5bbadc7539"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dc482a281a19a7d7e91ad1b2d551bb301c54d0e6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f971f1c63cf71579258360a12bd185bc1cd1a043"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98833.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98833"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"46b5889cc2c54bac7d7e727a44d28a298df23cef"},{"fixed":"95c8f36293c22d450c371167ad4f9a5bbadc7539"},{"fixed":"f971f1c63cf71579258360a12bd185bc1cd1a043"},{"fixed":"dc482a281a19a7d7e91ad1b2d551bb301c54d0e6"},{"fixed":"12b31d1acd20b3185bb5f0748db0cf6874c8e9d1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98833.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.7.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98833.json"}}],"schema_version":"1.9.0"}
