Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
dm: fix copying after src array boundaries
The blammed commit copied to argv the size of the reallocated argv, instead of the size of the old_argv, thus reading and copying from past the old_argv allocated memory.
