Re: [SECURITY] [DSA 2668-1] linux-2.6 security update
Saw this earlier, apparently there is a serious issue that affects all of the kernels up to 3.8 Will do a security thing tomorrow, if I get a chance, but it has been a while since we've had a look at it, my fault. Will update once I've reviewed.

The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2012-2121 Benjamin Herrenschmidt and Jason Baron discovered issues with the IOMMU mapping of memory slots used in KVM device assignment. Local users with the ability to assign devices could cause a denial of service due to a memory page leak. CVE-2012-3552 Hafid Lin reported an issue in the IP networking subsystem.

CVE-2012-6537 Mathias Krause discovered information leak issues in the Transformation user configuration interface. Local users with the CAP_NET_ADMIN capability can gain access to sensitive kernel memory. CVE-2012-6539 Mathias Krause discovered an issue in the networking subsystem. Local users on 64-bit systems can gain access to sensitive kernel memory. CVE-2012-6540 Mathias Krause discovered an issue in the Linux virtual server subsystem. Local users can gain access to sensitive kernel memory. Note: this issue does not affect Debian provided kernels, but may affect custom kernels built from Debian's linux-source-2.6.32 package. CVE-2012-6542 Mathias Krause discovered an issue in the LLC protocol support code. Local users can gain access to sensitive kernel memory. CVE-2012-6544 Mathias Krause discovered issues in the Bluetooth subsystem. Local users can gain access to sensitive kernel memory. CVE-2012-6545 Mathias Krause discovered issues in the Bluetooth RFCOMM protocol support. Local users can gain access to sensitive kernel memory.
