CVE-2016-3157

The switchto function in arch/x86/kernel/process64.c in the Linux kernel does not properly context-switch IOPL on 64-bit PV Xen guests, which allows local guest OS users to gain privileges, cause a denial of service guest OS crash, or obtain sensitive information by leveraging I/O port access...

kernel: partial ASLR bypass through TLS base addresses leak

An information leak flaw was found in the way the Linux kernel changed certain segment registers and thread-local storage TLS during a context switch. A local, unprivileged user could use this flaw to leak the user space TLS base address of an arbitrary process...

No description provided by source. source: http://www.securityfocus.com/bid/2529/info The Linux kernel is the core of all distributions of the Linux Operating System. It was originally written by Linus Torvalds, and is maintained by a community of developers. A problem in the Linux Kernel could...

CVE-2014-3125

Xen 4.4.x, when running on an ARM system, does not properly context switch the CNTKCTLEL1 register, which allows local guest users to modify the hardware timers and cause a denial of service crash via unspecified vectors...

CVE-2014-3125

CVE-2014-3125 concerns Xen 4.4.x on ARM where CNTKCTL_EL1 register is not properly context switched. This allows a local guest to modify hardware timers and, per the XSA-91 advisory, may enable a guest kernel to reconfigure timer interrupts for the entire system, potentially causing a denial of s...
