If a thread exits while holding a pending node refcount\nincrement (e.g. pushed as deferred work to that thread), the refcount\nincrement was previously dropped because Node::cancel() and\nNodeWrapper::cancel() were no-ops.\n\nDropping the refcount update leaves the node's delivery state and count\nstate desynchronized, and userspace will not receive the notification,\nwhich can cause the node to never be freed from the process's nodes tree\nwhen all external references are dropped.\n\nFix this by implementing DeliverToRead::cancel() for Node and NodeWrapper\nto move the pending refcount update to the process's work queue on thread\nexit so another thread can deliver it to userspace.","state":0,"publishedAt":"2026-10-23T12:23:18.83+00:00","modifiedAt":"2026-10-23T12:23:18.83+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/android/binder/node.rs\",\n                        \"drivers/android/binder/node/wrapper.rs\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"eafedbc7c050c44744fbdf80bdf3315e860b7513\",\n                            \"lessThan\": \"71cbad138969edecef01b28dff87d91b56db538d\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"eafedbc7c050c44744fbdf80bdf3315e860b7513\",\n                            \"lessThan\": \"fb0f8dfc5a030ed3d60a1d03acdc99c90ee99fc1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"eafedbc7c050c44744fbdf80bdf3315e860b7513\",\n                            \"lessThan\": \"2a74ccd1bcc170e66525f34e9de8652b57e2cf3d\",\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/android/binder/node.rs\",\n                        \"drivers/android/binder/node/wrapper.rs\"\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\": \"6.18.57\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.11\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/71cbad138969edecef01b28dff87d91b56db538d","https://git.kernel.org/stable/c/fb0f8dfc5a030ed3d60a1d03acdc99c90ee99fc1","https://git.kernel.org/stable/c/2a74ccd1bcc170e66525f34e9de8652b57e2cf3d"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-99075","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-99075","identifiers":["CVE-2026-99075"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
