Description
Description
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.
