Two major security flaws in the Linux kernel were reported last weekend. Both flaws have the same impact (root access for local users) and both exist within the vmsplice() system call, which was added to the kernel in 2.6.17. There is no configuration option to exclude vmsplice() so everyone is vulnerable.One of the security issues existed for the entire lifetime of vmsplice(), so any kernel version from 2.6.17 onwards is vulnerable. This was fixed in 22.214.171.124, 126.96.36.199 and 188.8.131.52. It has been assigned the vulnerability identifier of CVE-2008-0600.
