CVE-2026-74574

HIGH 7.8 ALL-YEARS

Published 2026-08-15 · Last modified 2026-10-16 · Linux · NVD: Received

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix fdev setup failure cleanup in idxd_cdev_open() The failed_dev_add and failed_dev_name paths drop the file-device reference while wq->wq_lock is still held. If put_device(fdev) drops the last reference, idxd_file_dev_release() runs synchronously and tries to take wq->wq_lock again, deadlocking. Those paths also fall through into the later ctx cleanup labels even though idxd_file_dev_release() owns that cleanup and frees ctx. This can make idxd_xa_pasid_remove(ctx) and kfree(ctx) operate on a freed context. Move idxd_wq_get() before file-device setup can fail, since the release callback always calls idxd_wq_put(). Then unlock wq->wq_lock before put_device(fdev) and return directly from the file-device setup failure path, leaving ctx cleanup to the release callback.

    • vendor fix: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. Red Hat recommends treating all kernel errata as security-relevant. Given the kernel's fundamental role, any bug has a higher chance of impacting system security, even if that impact only becomes clear after a fix is published. Therefore, Red Hat prioritizes delivering fixes that improve our customers' overall security posture. Because of this proactive approach, a patch may be associated with a CVE assignment at a future date. Retroactive CVE assignments are always documented in the corresponding errata and on Red Hat's CVE pages. We strongly advise against delaying updates, as doing so may leave your system exposed when protections are already available. Vendor guidance
    • workaround: The vulnerability resides in the `idxd` kernel module. If the Intel Data Streaming Accelerator (DSA) functionality is not actively used or required, the `idxd` module can be prevented from loading to mitigate this issue. To blacklist the module: 1. Create a new file `/etc/modprobe.d/blacklist-idxd.conf` with the following content: ``` blacklist idxd ``` 2. Regenerate the initramfs to ensure the blacklist takes effect on boot: ```bash sudo dracut -f -v ``` or for systems using `mkinitrd`: ```bash sudo mkinitrd -f /boot/initramfs-$(uname -r).img $(uname -r) ``` 3. Reboot the system for the changes to take effect. This mitigation may impact functionality that relies on the Intel Data Streaming Accelerator. If `idxd` functionality is required, this mitigation is not applicable.

    • workaround: The vulnerability resides in the `idxd` kernel module. If the Intel Data Streaming Accelerator (DSA) functionality is not actively used or required, the `idxd` module can be prevented from loading to mitigate this issue. To blacklist the module: 1. Create a new file `/etc/modprobe.d/blacklist-idxd.conf` with the following content: ``` blacklist idxd ``` 2. Regenerate the initramfs to ensure the blacklist takes effect on boot: ```bash sudo dracut -f -v ``` or for systems using `mkinitrd`: ```bash sudo mkinitrd -f /boot/initramfs-$(uname -r).img $(uname -r) ``` 3.
