CVE-2015-1420
Published: 16 March 2015
Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function.
From the Ubuntu security team
A race condition was discovered in the Linux kernel's file_handle size verification. A local user could exploit this flaw to read potentially sensative memory locations.
