Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A race condition exists in the way the kernel handles process links. The functions proc pid get link() and proc pid readlink() perform a task lookup from the pid, execute a ptrace access check, and then perform a second task lookup to grant access. This sequence creates a timing window that can be exploited.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
