Description:
Two vulnerabilities have been reported in the Linux kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service) or potentially gain escalated privileges.

1) Insufficient address validation in "ptrace()" on the AMD64 platform can be exploited to crash the kernel by setting an invalid segment base.

2) An error in the "mmap()" function may result in creation of memory maps with a start address after the end address. This can be exploited to cause a DoS or potentially gain escalated privileges.
