CVE-2024-36884

In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu: Use the correct type in nvidia_smmu_context_fault() This was missed because of the function pointer indirection. nvidia_smmu_context_fault() is also installed as a irq function, and the 'void *' was changed to a struct arm_smmu_domain. Since the iommu_domain is embedded at a non-zero offset this causes nvidia_smmu_context_fault() to miscompute the offset. Fixup the types.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: iommu/arm-smmu: use el tipo correcto en nvidia_smmu_context_fault() Esto se omitió debido a la dirección indirecta del puntero de función. nvidia_smmu_context_fault() también está instalado como una función irq, y 'void *' se cambió a una estructura arm_smmu_domain. Dado que iommu_domain está incrustado en un desplazamiento distinto de cero, esto hace que nvidia_smmu_context_fault() calcule mal el desplazamiento. Arregle los tipos.
