Vasiliy Kulikov discovered that the Bluetooth stack did not correctly check that device name strings were NULL terminated. A local attacker could exploit this to crash the system, leading to a denial of service, or leak contents of kernel stack memory, leading to a loss of privacy. It was discovered that the Linux kernel on ARM processors allowed a tracing process to modify a syscall after a seccomp decision had been made on that syscall. A local attacker could possibly use this to bypass seccomp restrictions. Various other issues were also addressed.

e35a8f609b986bb8b2fc490b895224847eba088cf1f87974f9bc5820e0c3c589Ubuntu Security Notice 1256-1 - It was discovered that the /proc filesystem did not correctly handle permission changes when programs executed. A local attacker could hold open files to examine details about programs running with higher privileges, potentially increasing the chances of exploiting additional vulnerabilities. Vasiliy Kulikov discovered that the Bluetooth stack did not correctly clear memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Various other issues were also addressed.

A local attacker could exploit this to read uninitialized data from the disk, leading to a loss of privacy. Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values. By inserting a specially crafted disk device, a local attacker could exploit this to gain root privileges. Various other issues were also addressed.

A local attacker could exploit this to gain root privileges. Dan Rosenberg discovered that multiple terminal ioctls did not correctly initialize structure memory. A local attacker could exploit this to read portions of kernel stack memory, leading to a loss of privacy. Various other issues were also addressed.

4651fa67004a9e7d7332ee7abc2daad2af631e68a48c132d8217d95854217ba6Red Hat Security Advisory 2011-0833-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw in the dccp_rcv_state_process() function could allow a remote attacker to cause a denial of service, even when the socket was already closed. Multiple buffer overflow flaws were found in the Linux kernel's Management Module Support for Message Passing Technology based controllers. A local, unprivileged user could use these flaws to cause a denial of service, an information leak, or escalate their privileges. Various other issues were also addressed.
