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. (NVD)
