Vulnerability description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The mem_write function in the Linux kernel before 3.2.2, when ASLR is disabled, does not properly check permissions when writing to /proc/<pid>/mem, which allows local users to gain privileges by modifying process memory, as demonstrated by Mempodipper.
