Vulnerability Data

In the Linux kernel before 6.0.3, drivers/gpu/drm/virtio/virtgpu_object.c misinterprets the drm_gem_shmem_get_sg_table return value (expects it to be NULL in the error case, whereas it is actually an error pointer).

finds

Security testing can detect and correct cases where one component misinterprets another’s state or messages.

prevents

Secure development lifecycle can require consistent interface contracts and canonicalization rules that reduce interpretation conflicts between components.

prevents

Explicit application security requirements can mandate unambiguous protocol and data-format specifications that prevent divergent interpretations.

prevents

Secure architecture principles include well-defined component boundaries and shared data models that limit conflicting state perceptions.

prevents

Secure coding standards can enforce canonical input handling and strict protocol compliance to avoid misinterpretation between products.
