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

iommu/tegra241-cmdqv: Don't fall back to a freed smmu after devm_krealloc()

__tegra241_cmdqv_probe() uses devm_krealloc() to grow @smmu into the larger

tegra241_cmdqv, which frees the original @smmu once it relocates. A failure

after that returned NULL, and the caller then dereferenced the freed @smmu

on its fallback path.

Return an int and take @smmu by reference instead, then update *smmu to the

reallocated pointer after devm_krealloc() succeeds, so the caller and its

fallback path both use the live @smmu rather than the freed original. (NVD)
