Overview

CVE-2026-74606 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:

eventfs: Fix use-after-free in eventfs_remove_rec()

eventfs_remove_rec() recursively removes the child at the current loop

position. After the recursive call returns, list_for_each_entry() advances

by reading list.next from the removed child.

If free_ei() drops the final reference, release_ei() reuses the list/rcu

union to queue an SRCU callback. The child may be freed before that read.

The eventfs_mutex serializes list updates, but it does not keep the removed

child alive or prevent the SRCU callback from running.

Use list_for_each_entry_safe() to save the next sibling before recursively

removing the current child.

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.
