{"id":"CVE-2026-93199","summary":"i3c: master: Do not treat master device as a duplicate target","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ni3c: master: Do not treat master device as a duplicate target\n\ni3c_master_search_i3c_dev_duplicate() searches the bus for another I3C\ndevice with the same PID as the reference device.  The search can match\nmaster-\u003ethis, causing the controller itself to be returned as a\nduplicate.\n\nSince the controller is not a target device, it cannot be a duplicate of\none.  Exclude master-\u003ethis from matching so that the function only\nreturns real duplicate target devices.","modified":"2026-09-19T03:47:26.968154490Z","published":"2026-09-17T16:12:21.081Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93199.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/150e71808d3715a0deefbb189c780d03fdbdc735"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4dc1b3eeba7991905a5b5b8129ebea51be7d87b7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d0cc00957292e353ad46039034cd8f82fc4f8057"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93199.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93199"},{"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":"3a379bbcea0af6280e1ca0d1edfcf4e68cde6ee0"},{"fixed":"d0cc00957292e353ad46039034cd8f82fc4f8057"},{"fixed":"150e71808d3715a0deefbb189c780d03fdbdc735"},{"fixed":"4dc1b3eeba7991905a5b5b8129ebea51be7d87b7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93199.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93199.json"}}],"schema_version":"1.9.0"}
