- Details

In the Linux kernel, the following vulnerability has been resolved:
virtio-blk: fix implicit overflow on virtiomaxdma_size
The following codes have an implicit conversion from sizet to u32: (u32)maxsize = (sizet)virtiomaxdmasize(vdev);
This may lead overflow, Ex (sizet)4G -> (u32)0. Once virtiomaxdmasize() has a larger size than U32MAX, use U32MAX instead.
