Hi All,
This is an inform distro maintainers about recently upstreamed
hardening
against speculative execution attacks using BPF JIT spraying.
The backports are available here:

6.1 backport is queued. Others are part of LTS kernels.
5.15 and older do not support pack allocator for BPF on which the
hardening
is based on. So the series is not directly applicable to 5.15 and
older,
and may need custom hardening patches.
Any patches out there for kernel 5.17.15? Thanks in advance!
Please let me know if there are any questions.
Thanks,
Pawan
