"value": "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."

"value": "AV:L - The vulnerable interface is reached through local open and ioctl syscalls on /dev/qat_adf_ctl; it has no network or physical entry path.\nAC:L - The attacker can repeatedly invoke the start or status ioctl while coordinating QAT VF teardown in a hot-pluggable deployment, giving effective control over the race. A short ioctl loop has already produced the confirmed [KASAN use-after-free](https://www.spinics.net/lists/kernel/msg6034466.html ).\nPR:L - The driver performs no capability or credential check, so device-file permissions are the only gate. Standard QAT installation grants non-root qat-group members mode-0660 access to qat_adf_ctl according to the [Intel QAT installation guide](https://intel.github.io/quickassist/GSG/2.X/installation.html ).\nUI:N - Exploitation requires only attacker-generated ioctl calls and device-lifecycle operations, with no action by another user.\nS:U - The flaw compromises the same host or guest kernel security authority in which the vulnerable QAT driver executes; ordinary kernel privilege escalation does not change scope.\nC:H - The freed accel_dev can be reclaimed with attacker-influenced heap contents, and the status path follows stale pointers and invokes callbacks, providing a defensible route to arbitrary kernel-memory disclosure.\nI:H - Mutex operations and configuration paths write through the reclaimed object, while forged hw_device callbacks provide a plausible control-flow-hijack and arbitrary-kernel-write primitive.\nA:H - The UAF is confirmed to cause a KASAN kernel failure, and repeated malformed ioctls can independently create a printk storm leading to stalls, watchdog lockups, or panic."
