{"id":"CVE-2026-93143","summary":"staging: media: ipu7: fix pm_runtime refcount leak in ipu7_resume()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: media: ipu7: fix pm_runtime refcount leak in ipu7_resume()\n\nipu7_resume() calls pm_runtime_get_sync() before resuming the device.\nIf the runtime PM resume fails, the usage count remains incremented, but\nthe error path returns without dropping the reference.\n\nUse pm_runtime_resume_and_get() instead, which balances the usage count\non failure and avoids the leak. Keep returning 0 on error, as resume\ncallbacks should not propagate failures to the PM core, matching the\nbehaviour of the ipu6 driver.","modified":"2026-09-19T03:47:31.537831723Z","published":"2026-09-17T16:11:42.099Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93143.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/437d6d15936db87485afabf7d52754b7b19cc787"},{"type":"WEB","url":"https://git.kernel.org/stable/c/593fda71983b9c23c84a566b20c53dc402c6b376"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b298b80814dd0fc3cb1c8c0e0082fc14fdb5fecf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93143.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93143"},{"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":"b7fe4c0019b12d60ece3e99eeb0ccfd5a1d103e5"},{"fixed":"593fda71983b9c23c84a566b20c53dc402c6b376"},{"fixed":"437d6d15936db87485afabf7d52754b7b19cc787"},{"fixed":"b298b80814dd0fc3cb1c8c0e0082fc14fdb5fecf"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93143.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.17.0"},{"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-2026-93143.json"}}],"schema_version":"1.9.0"}
