Description:
A vulnerability and a weakness have been reported in Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
1) An error exists when the kernel returns program control using SYSRET on Intel EM64T CPUs. The may cause a DoS due to the way Intel EM64T CPUs handle uncanonical return addresses when a user has been able to change the frames.
2) Improperly use of BUG_ON in the "__group_complete_signal()" function may in certain cases be exploited to cause unwanted process crashes.
