Linux kernel (Quantal HWE) regression

[MEDIUM] Linux kernel (Quantal HWE) regression
Title: Linux kernel (Quantal HWE) regression
Summary: USN-1704-1 introduced a regression in the Linux kernel.
USN-1704-1 fixed vulnerabilities in the Linux kernel. Due to an unrelated
regression inotify/fanotify stopped working after upgrading. This update
fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Brad Spengler discovered a flaw in the Linux kernel's uname system call. An
unprivileged user could exploit this flaw to read kernel stack memory.
(CVE-2012-0957)
Jon Howell reported a flaw in the Linux kernel's KVM (Kernel-based virtual
machine) subsystem's handling of the XSAVE feature. On hosts, using qemu
userspace, without the XSAVE feature an unprivileged local attacker could
exploit this flaw to crash the system. (CVE-2012-4461)

Summary: The system could be made to crash under certain conditions.
A flaw was discovered in the Linux kernel's handling of new hot-plugged
memory. An unprivileged local user could exploit this flaw to cause a
denial of service by crashing the system.
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel
