Since the\nsuperseded transaction was never delivered, binder_apply_fd_fixups() was\nnever called and no fds were installed in the target process.\n\nWith is_failure=false, the BINDER_TYPE_FDA cleanup handler interprets\nstale buffer contents as installed fd numbers and passes them to\nbinder_deferred_fd_close(), closing unrelated file descriptors.\n\nPass is_failure=true since the transaction was never delivered to the\ntarget, matching the semantics of all other undelivered-transaction\ncleanup paths.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1ab671b50714ad8e359cf37eb041d8044319ccdc","tags":[]},{"url":"https://git.kernel.org/stable/c/22c135635fdd9816c0ef140d6de7b2e4fdf73e89","tags":[]},{"url":"https://git.kernel.org/stable/c/60a9f7323ae7318a7cce0d387c318da24f1e8726","tags":[]},{"url":"https://git.kernel.org/stable/c/86cdcc87d4ba60aebf94ba3346b3c900c5cd79ff","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
