Description

In the Linux kernel, the following vulnerability has been resolved:

drm/etnaviv: check for reaped mapping in etnaviv_iommu_unmap_gem

When the mapping is already reaped the unmap must be a no-op, as we would otherwise try to remove the mapping twice, corrupting the involved data structures.
