{"id":"CVE-2026-98973","summary":"drm/bridge: Fix unlocked list_del in drm_bridge_add()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/bridge: Fix unlocked list_del in drm_bridge_add()\n\nWhen re-adding a bridge that was previously removed, drm_bridge_add()\ndrops it from bridge_lingering_list without holding bridge_lock.\n\nBoth bridge_list and bridge_lingering_list are protected by bridge_lock,\nas they are concurrently modified by drm_bridge_remove() and\n__drm_bridge_free(), and walked by the debugfs 'bridges' file.  Running\nthe list_empty() test and the list_del_init() outside of the lock may\ntherefore corrupt either list.\n\nPerform both under bridge_lock.","modified":"2026-10-25T02:47:29.839079867Z","published":"2026-10-23T12:19:46.458Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98973.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/b62e3db8cdc1680e1c3390591e872f485148541a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f469d850854101eae60dd4080244f114a9bcf2b5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98973.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98973"},{"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":"17805a15d1751f5d6bb06f924f9bed216feb8db7"},{"fixed":"f469d850854101eae60dd4080244f114a9bcf2b5"},{"fixed":"b62e3db8cdc1680e1c3390591e872f485148541a"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98973.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98973.json"}}],"schema_version":"1.9.2"}
