Ubuntu Security Notice 3422-2 - USN-3422-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 LTS. It was discovered that a buffer overflow existed in the Bluetooth stack of the Linux kernel when handling L2CAP configuration responses. A physically proximate attacker could use this to cause a denial of service. Various other issues were also addressed.

A physically proximate attacker could use this to cause a denial of service. It was discovered that the asynchronous I/O subsystem of the Linux kernel did not properly set permissions on aio memory mappings in some situations. An attacker could use this to more easily exploit other vulnerabilities. Various other issues were also addressed.
59a73826987ffa71daea232f292915ef55c02017c0d971591db5164b7d4e6e9dRed Hat Security Advisory 2017-2669-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: A race condition was found in the Linux kernel, present since v3.14-rc1 through v4.12. The race happens between threads of inotify_handle_event() and vfs_rename() while running the rename operation against the same file. As a result of the race the next slab data or the slab's free list pointer can be corrupted with attacker-controlled data, which may lead to the privilege escalation.

Security Fix: An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system. A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A local user could use this flaw to crash the system or, potentially, escalate their privileges.

This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 17.04 for Ubuntu 16.04 LTS. Please note that this update changes the Linux HWE kernel to the 4.10 based kernel from Ubuntu 17.04, superseding the 4.8 based HWE kernel from Ubuntu 16.10. Ben Harris discovered that the Linux kernel would strip extended privilege attributes of files when performing a failed unprivileged system call. A local attacker could use this to cause a denial of service. Various other issues were also addressed.

A local attacker could use this to cause a denial of service. Andrey Konovalov discovered an out-of-bounds access in the IPv6 Generic Routing Encapsulation tunneling implementation in the Linux kernel. An attacker could use this to possibly expose sensitive information. Various other issues were also addressed.
