Now that\n__dpll_device_change_ntf() is exported for callers that already\nhold dpll_lock, use it directly and remove the change_work\ninfrastructure entirely.\n\nThis eliminates a race condition where change_work could be\nre-scheduled after cancel_work_sync() during device teardown,\npotentially causing the handler to dereference a freed or NULL\ndpll_dev pointer.","state":0,"publishedAt":"2026-07-19T14:56:01.889+00:00","modifiedAt":"2026-10-19T20:18:00.021+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/dpll/zl3073x/dpll.c\",\n                        \"drivers/dpll/zl3073x/dpll.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"9363b4837659d1b7ee04cfa714373ce4b4b8269f\",\n                            \"lessThan\": \"e7a33807fb3f87a855993474ac21684ce105927b\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"9363b4837659d1b7ee04cfa714373ce4b4b8269f\",\n                            \"lessThan\": \"d733f519f6443540f8359461a34e3b0042099bbe\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/dpll/zl3073x/dpll.c\",\n                        \"drivers/dpll/zl3073x/dpll.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.18\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.18\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.0.12\",\n                            \"lessThanOrEqual\": \"7.0.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.1\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/e7a33807fb3f87a855993474ac21684ce105927b","https://git.kernel.org/stable/c/d733f519f6443540f8359461a34e3b0042099bbe"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-63977","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-63977","identifiers":["CVE-2026-63977"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
