Monday morning Linux kernel news

It’s kernel update time. This is the single security bug fix edition:

We (the -stable team) are announcing the release of the 2.6.22.7 kernel. It contains a single security bugfix for the x86_64 architecture. There is potential for local privilege escalation, so all x86_64 users are certainly encouraged to upgrade.

CVE-2007-4573: x86_64: Zero extend all registers after ptrace in 32bit entry path.

I’ll also be replying to this message with a copy of the patch between 2.6.22.6 and 2.6.22.7.

I’m going to go out on a limb and guess this won’t be the last we hear from lwn.net.
