CVE ID :CVE-2026-64529<\/p>\n
Published : July 25, 2026, 10:17 a.m. | 1\u00a0hour, 34\u00a0minutes ago<\/p>\n
Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
crypto: qat – remove unused character device and IOCTLs<\/p>\n
The 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.<\/p>\n
The ioctl interface also increases the attack surface and is the
\nsubject of a number of bug reports.<\/p>\n
Remove 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.<\/p>\n
Clean 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.<\/p>\n
Additionally, drop the entry associated to QAT IOCTLs in
\nioctl-number.rst.<\/p>\n
Severity: 0.0 | NA<\/p>\n
