In the Linux kernel, the following vulnerability has been resolved:
iommu/riscv: prevent NULL deref in iovatophys
The riscviommupte_fetch() function returns either NULL for unmapped/never-mapped iova, or a valid leaf pte pointer that requires no further validation.
riscviommuiovatophys() failed to handle NULL returns. Prevent null pointer dereference in riscviommuiovatophys(), and remove the pte validation.
