{"id":"CVE-2026-98679","summary":"iio: accel: kxcjk-1013: reject duplicate event disable","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: accel: kxcjk-1013: reject duplicate event disable\n\nThe IIO core does not filter duplicate writes to the event enable\nattribute. kxcjk1013_write_event_config() already ignores repeated\nenable requests, but a repeated disable request still calls\nkxcjk1013_set_power_state(data, false), dropping a runtime PM reference\nthat was not acquired for this request. This can underflow the runtime\nPM usage count and trigger a \"Runtime PM usage count underflow\" warning.\n\nReturn early when the requested state already matches ev_enable_state.","modified":"2026-11-04T14:27:28.962564760Z","published":"2026-10-18T15:45:38.283Z","related":["SUSE-SU-2026:5091-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98679.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/137c35cff4d4d69f73cbfc0bf7870bf379a7a364"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2f9f88da802733bab7a87a0e685c8cfa7488f6ac"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3365209e758c845a197211645731f0e393a86012"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8c6d1abaff5dbbe2d2b7529de7f1f2395a2f07e9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aa94a37b5a3e560c277dac6f9e5d0d75549a6583"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ad690c0c1b9131725619e352cb7c970488cbf436"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b33dfdc0f22dd6c9cb9ae34a32723ef0a5d2ccf5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dd30c10ff60d2b30386c23bb7c61cc97f2385c97"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98679.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98679"},{"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":"b4b491c0832ef90a7a5070e5975bc8427f2049ca"},{"fixed":"b33dfdc0f22dd6c9cb9ae34a32723ef0a5d2ccf5"},{"fixed":"8c6d1abaff5dbbe2d2b7529de7f1f2395a2f07e9"},{"fixed":"2f9f88da802733bab7a87a0e685c8cfa7488f6ac"},{"fixed":"137c35cff4d4d69f73cbfc0bf7870bf379a7a364"},{"fixed":"ad690c0c1b9131725619e352cb7c970488cbf436"},{"fixed":"3365209e758c845a197211645731f0e393a86012"},{"fixed":"aa94a37b5a3e560c277dac6f9e5d0d75549a6583"},{"fixed":"dd30c10ff60d2b30386c23bb7c61cc97f2385c97"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98679.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.18.0"},{"fixed":"5.10.273"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.224"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.191"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"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/osv-test-cve-osv-conversion/osv-output/CVE-2026-98679.json"}}],"schema_version":"1.9.2"}
