Re: [PATCH 0/3] kexec: Fix invalid field access

Hello:

This series was applied to riscv/linux.git (for-next)
by Paul Walmsley [off-list ref]:

The kexec_buf structure was previously declared without initialization.
commit bf454ec31add ("kexec_file: allow to place kexec_buf randomly")

This is also triggering a UBSAN warning when the uninitialized data was
accessed:

Here is the summary with links:
