Answer in brief
CVE-2026-74328 records a Unknown severity vulnerability in iommufd: Destroy the pages content after detaching from dmabuf. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: iommufd: Destroy the pages content after detaching from dmabuf Sashiko points out this has gotten out of order, the mutex could still be in use through the dmabuf invalidation callbacks. Don't destroy any of the pages content until the dmabuf is fully detached.
