CVE-2012-2745
Published: 09 August 2012
The copy_creds function in kernel/cred.c in the Linux kernel before 3.3.2 provides an invalid replacement session keyring to a child process, which allows local users to cause a denial of service (panic) via a crafted application that uses the fork system call.
From the Ubuntu security team
A flaw was found in how the Linux kernel passed the replacement session keyring to a child process. An unprivileged local user could exploit this flaw to cause a denial of service (panic).
