kernel-2.6.18-308.3.AXS3

The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.

Security issues fixed with this release:

CVE-2012-1583
Double free vulnerability in the xfrm6_tunnel_rcv function in net/ipv6/xfrm6_tunnel.c in the Linux kernel before 2.6.22, when the xfrm6_tunnel module is enabled, allows remote attackers to cause a denial of service (panic) via crafted IPv6 packets.

CVE-2012-0217
The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; and Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. NOTE: this description clearly does not belong in CVE, because a single entry cannot be about independent codebases; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier.

Fixed bugs:

Some machines would hang at start up when "nmi_watchdog=1" was added to the boot parameter. This has been fixed by disabling the i8042 driver.

Improved the support of Intel Sandy Bridge GPUs.
