kernel: block: initialize integrity buffer to zero before writing it to media
A flaw was found in the Linux kernel, where it initialized the integrity buffer to zero before writing it to media. Metadata added by biointegrityprep uses plain kmalloc, which leads to random kernel memory being written. Protection Information PI metadata is limited to the app tag not used by...
