Answer in brief
CVE-2026-74380 records a Unknown severity vulnerability in gpu: host1x: Fix iommu_map_sgtable() return value check. 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: gpu: host1x: Fix iommu_map_sgtable() return value check Commit "iommu: return full error code from iommu_map_sg[_atomic]()" changed iommu_map_sgtable() to return an ssize_t and negative values in error cases, rather than a size_t and a zero. pin_job() also was incorrectly assigning to 'int', which could cause overflows into negative values. Update pin_job() to correctly check for errors from iommu_map_sgtable.
