CVE-2026-64153 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix iommu_map_sgtable() return value check and avoid WARN 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. Store the return value in the appropriate type and in case of error, return it rather than WARNing. Patchwork: https://patchwork.freedesktop.org/patch/719685/
A vulnerability in the Linux kernel's DRM MSM component has been addressed. The issue arose because the IOMMU mapping function was not properly handling error return values. Instead of returning a negative error code when an issue occurred, it would issue a warning and return a zero, which could lead to incorrect behavior. This vulnerability affects the Linux kernel stable tree.
The vulnerability has been fixed in the Linux kernel. Users can apply the latest patches available in the Linux kernel stable tree to address this issue.
