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...

golang-fips: Golang FIPS zeroed buffer

A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted...
