Summary
block: initialize integrity buffer to zero before writing it to media
Details

In the Linux kernel, the following vulnerability has been resolved:

block: initialize integrity buffer to zero before writing it to media

Metadata added by biointegrityprep is using plain kmalloc, which leads to random kernel memory being written media. For PI metadata this is limited to the app tag that isn't used by kernel generated metadata, but for non-PI metadata the entire buffer leaks kernel memory.

Fix this by adding the _GFPZERO flag to allocations for writes.
