kernel: x86: local privesc due to bad_iret and paranoid entry incompatibility
A flaw was found in the way the Linux kernel handled GS segment register base switching when recovering from a SS stack segment fault on an erroneous return to user space. A local, unprivileged user could use this flaw to escalate their privileges on the system...

UBUNTU-CVE-2014-5148
Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to...

Linux Kernel ptrace/sysret - 本地提权漏洞
No description provided by source. / CVE-2014-4699 ptrace/sysret PoC by Vitaly Nikolenko [email protected] gcc -O2 pocv0.c This code is kernel specific. On Ubuntu 12.04.0 LTS 3.2.0-23-generic, the following will trigger the GP in sysret and overwrite the PF handler so we can land to our NOP sled...
Linux Kernel ptrace/sysret - Local Privilege Escalation Exploit
The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service double...

Kernel: net: leakage of uninitialized memory to user-space via recv syscalls
The pnrecvmsg function in net/phonet/datagram.c in the Linux kernel before 3.12.4 updates a certain length value before ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel stack memory via a 1 recvfrom, 2 recvmmsg, ...
