{"schema":"threatline.record/2","record":{"id":"CVE-2026-98779","aliases":[],"summary":"drm/amdgpu: fix ACP MFD device leak on init failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: fix ACP MFD device leak on init failure\n\nacp_hw_init() registers ACP child devices with mfd_add_devices() before\nattaching them to the ACP power domain and initializing the hardware.\n\nIf attaching a child to the power domain fails, or if the ACP reset or\nclock enable operation times out, the failure path frees only the\nsource cell, resource, and platform-data allocations. 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)","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98779","source_modified_at":"2026-10-21T12:56:52.904Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"d700c26ed64bd3c26e4aa7679b9d5f3333c3747a","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"2b9a53940a2bc063ea4cd09ee49220a503a0170c","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"587469076e4ffb617f7ad1a0c4a13072a3e87113","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"abf854513bc19e6e24d45353ac99ec5627ee0acc","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"f0013046151b7467e62c471c1c83d63ea255799c","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98779","source_modified_at":"2026-10-21T12:56:52.904Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"4.6","status":"affected"},{"version":"0","lessThan":"4.6","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98779","source_modified_at":"2026-10-21T12:56:52.904Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"2b9a53940a2bc063ea4cd09ee49220a503a0170c","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98779","source_modified_at":"2026-10-21T12:56:52.904Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"587469076e4ffb617f7ad1a0c4a13072a3e87113","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05729,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:48:16.729Z","modified_at":"2026-10-21T12:56:52.904Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98779","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:56:52.904Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98779","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/d700c26ed64bd3c26e4aa7679b9d5f3333c3747a"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/2b9a53940a2bc063ea4cd09ee49220a503a0170c"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/587469076e4ffb617f7ad1a0c4a13072a3e87113"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/abf854513bc19e6e24d45353ac99ec5627ee0acc"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/f0013046151b7467e62c471c1c83d63ea255799c"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T12:56:52.904Z","content_hash":"1554abe9aec6c419b5a9fefd6a20e8c16e933c4c4a14cb3fbbb08ff67c258339"}}
