Ubuntu Security Notice 1186-1 - Dan Rosenberg discovered that IPC structures were not correctly initialized on 64bit systems. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Steve Chen discovered that setsockopt did not correctly check MSS values. A local attacker could make a specially crafted socket call to crash the system, leading to a denial of service. Vladymyr Denysov discovered that Xen virtual CD-ROM devices were not handled correctly. A local attacker in a guest could make crafted blkback requests that would crash the host, leading to a denial of service. Various other issues were also addressed.

A local attacker could exploit this to gain root privileges. Dan Rosenberg discovered that the CAN protocol on 64bit systems did not correctly calculate the size of certain buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. Various other issues were also addressed.

Gleb Napatov discovered that KVM did not correctly check certain privileged operations. Dan Jacobson discovered that ThinkPad video output was not correctly access controlled. Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did not correctly clear kernel memory. Nelson Elhage discovered that the Linux kernel IPv4 implementation did not properly audit certain bytecodes in netlink messages. Dan Rosenberg discovered that the USB subsystem did not correctly initialize certain structures. Various other issues have also been addressed.

A local attacker with access to a guest kernel could exploit this to crash the host system, leading to a denial of service. Steve Chen discovered that setsockopt did not correctly check MSS values. A local attacker could make a specially crafted socket call to crash the system, leading to a denial of service. Dave Jones discovered that the mprotect system call did not correctly handle merged VMAs. A local attacker could exploit this to crash the system, leading to a denial of service. Vegard Nossum discovered that memory garbage collection was not handled correctly for active sockets. A local attacker could exploit this to allocate all available kernel memory, leading to a denial of service.
