Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
block: validate user space vectors during extraction
The bio-based drivers don’t necessarily check the alignment split, and stacking block drivers don’t always handle a misalignment detected after submitting the bio. Validate user vectors against the device’s dma_alignment as the bio is built from the iov_iter, rejecting misaligned early with -EINVAL.
