CVE-2026-90427 | BDVDB-2026-376205 Detail

Description#

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.
