CVE-2015-1420 (retired)

Priority
Description
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.
Ubuntu-Description
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.
