Description Prasad Pandit 2014-05-12 12:16:18 UTC

Linux kernel built with the BPF interpreter support in the networking core is
vulnerable to an out of bounds buffer access flaw. It occurs when accessing a
netlink attribute from the skb->data buffer. It could lead to DoS via kernel
crash or leakage of kernel memory bytes to user space.

An unprivileged user/program could use this flaw to crash the system kernel
resulting in DoS or leak kernel memory bytes to user space.
