The child\nplatform devices already registered by mfd_add_devices() remain\nregistered and are never released.\n\nRemove the children from the power domain and unregister the MFD\ndevices on failures that occur after mfd_add_devices() succeeds. Keep\nmfd_add_devices() failures on the existing cleanup path since the MFD\ncore already rolls back partially registered children itself.\n\nThe issue was identified by a static analysis tool I developed and\nconfirmed by manual review.\n\n(cherry picked from commit 63da68d6a2279ec945581c990c5a59a5ae8b5560)","score":null,"severity":"unknown","published":"2026-10-18T15:48:16.729Z","modified":"2026-10-30T12:39:46.267Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"25030321ba2860c56651429a4f28d94a6483d952","status":"affected","lessThan":"385ad314f1c096aae71fff516214bb312a6047fb","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","status":"affected","lessThan":"7b7f770f48be77ce38e93216983dcdf1ea3a42ba","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","status":"affected","lessThan":"65ef6645982ccde16a7bc98d025eb80f5fab47f6","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","status":"affected","lessThan":"d700c26ed64bd3c26e4aa7679b9d5f3333c3747a","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","status":"affected","lessThan":"2b9a53940a2bc063ea4cd09ee49220a503a0170c","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","status":"affected","lessThan":"587469076e4ffb617f7ad1a0c4a13072a3e87113","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","status":"affected","lessThan":"abf854513bc19e6e24d45353ac99ec5627ee0acc","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","status":"affected","lessThan":"f0013046151b7467e62c471c1c83d63ea255799c","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98779"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"4.6","status":"affected"},{"version":"0","status":"unaffected","lessThan":"4.6","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.224","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.113","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.56","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.10","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98779"}],"remediation":[],"references":["https://git.kernel.org/stable/c/385ad314f1c096aae71fff516214bb312a6047fb","https://git.kernel.org/stable/c/7b7f770f48be77ce38e93216983dcdf1ea3a42ba","https://git.kernel.org/stable/c/65ef6645982ccde16a7bc98d025eb80f5fab47f6","https://git.kernel.org/stable/c/d700c26ed64bd3c26e4aa7679b9d5f3333c3747a","https://git.kernel.org/stable/c/2b9a53940a2bc063ea4cd09ee49220a503a0170c","https://git.kernel.org/stable/c/587469076e4ffb617f7ad1a0c4a13072a3e87113","https://git.kernel.org/stable/c/abf854513bc19e6e24d45353ac99ec5627ee0acc","https://git.kernel.org/stable/c/f0013046151b7467e62c471c1c83d63ea255799c"],"sources":[{"name":"CVE","id":"CVE-2026-98779","modified":"2026-10-30T12:39:46.267Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98779"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T13:09:10.046Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T00:00:32.242Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
