CVE-2026-74277

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the iommu dma map sg() function when handling PCI P2PDMA cases. The DMA length of the current scatterlist segment s is incorrectly assigned from the head entry sg->length instead of the current entry s->length. This error causes all P2PDMA segments in the scatterlist to inherit the length of the first segment, resulting in corrupted DMA lengths for multi-segment scatterlists.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
