      "title": "crypto: qat - remove unused character device and IOCTLs",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: qat - remove unused character device and IOCTLs\n\nThe QAT driver exposes a character device (qat_adf_ctl) with IOCTLs\nfor device configuration, start, stop, status query and enumeration.\nThese IOCTLs are not part of any public uAPI header and have no known\nin-tree or out-of-tree users. Device lifecycle is already managed via\nsysfs.\n\nThe ioctl interface also increases the attack surface and is the\nsubject of a number of bug reports.\n\nRemove the character device, the IOCTL definitions, and the related\ndata structures (adf_dev_status_info, adf_user_cfg_key_val,\nadf_user_cfg_section, adf_user_cfg_ctl_data). Drop the now-unused\nadf_cfg_user.h header and strip adf_ctl_drv.c down to the minimal\nmodule_init/module_exit hooks for workqueue, AER, and crypto/compression\nalgorithm registration.\n\nClean up leftover dead code that was only reachable from the removed\nIOCTL paths: adf_cfg_del_all(), adf_devmgr_verify_id(),\nadf_devmgr_get_num_dev(), adf_devmgr_get_dev_by_id(),\nadf_get_vf_real_id() and the unused ADF_CFG macros.\n\nAdditionally, drop the entry associated to QAT IOCTLs in\nioctl-number.rst.",
