Description of the vulnerability

The Linux kernel supports the Copy On Write operation, which is used to copy memory only when it is modified.

However, a local attacker can manipulate the memory, so the COW operation writes in Read Only memory.

A local attacker can therefore generate a memory corruption via a Copy On Write on the Linux kernel, in order to trigger a denial of service, and possibly to run code.
