Overview

CVE-2026-74725 is a high-severity vulnerability. It was published on August 22, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

enic: fix tx_hang_reset use-after-free on device removal

enic_remove() cancels the reset and change_mtu_work items but does not

cancel tx_hang_reset. A TX timeout that fires while the device is being

removed can schedule enic_tx_hang_reset() so that it runs after

free_netdev(), resulting in a use-after-free.

cancel_work_sync() alone is not sufficient here: the still-live watchdog

and notify paths can re-schedule these work items in the window between

the cancel and unregister_netdev(). Use disable_work_sync(), which

cancels the work and blocks any subsequent schedule_work() from

requeuing it, and apply it to the reset and change_mtu_work items as

well so the same requeue race is closed for all teardown work.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
