Permissions, Privileges, and Access Controls in Linux kernel - CVE-2012-0028

Vulnerability details

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

The robust futex implementation in the Linux kernel before 2.6.28 does not properly handle processes that make exec system calls, which allows local users to cause a denial of service or possibly gain privileges by writing to a memory location in a child process.
