Answer in brief
CVE-2026-74420 records a Unknown severity vulnerability in drm/gpusvm: Reject VMAs with VM_IO or VM_PFNMAP when creating SVM ranges. 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: drm/gpusvm: Reject VMAs with VM_IO or VM_PFNMAP when creating SVM ranges VMAs marked with VM_IO or VM_PFNMAP are not backed by struct page objects, which GPUSVM requires in order to operate correctly. In particular, get_pages() relies on hmm_range_fault() to resolve struct pages for the target range. Attempting to create an SVM range on such VMAs results in repeated get_pages() failures and can lead to an infinite loop inside a driver’s page‑fault handler. Prevent this by rejecting ranges on VM_IO or VM_PFNMAP VMAs and returning -EIO.
