Synopsis: Important: kernel security and bug fix update Issue Date: 2012-05-29 CVE Numbers: CVE-2012-2136 The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: * It was found that the data_len parameter of the sock_alloc_send_pskb() function in the Linux kernel's networking implementation was not validated before use. A local user with access to a TUN/TAP virtual interface could use this flaw to crash the system or, potentially, escalate their privileges. Note that unprivileged users cannot access TUN/TAP devices until the root user grants them access. (CVE-2012-2136, Important) We have also posted updated kernel-module-* packages corresponding to this kernel version. The system must be rebooted for this update to take effect.
