SUSE has issued an update for the kernel. This fixes some vulnerabilities, which can be exploited by malicious, local users to cause a DoS (Denial of Service) and disclose potentially sensitive information, and by malicious people to cause a DoS.
1) An error while copying memory from userspace can be exploited to disclose potentially sensitive information.
2) A use-after-free error exists within the "tcp_rcv_state_process()" function, which can be exploited to cause a kernel crash by e.g. sending a specially crafted IPv6 packet to a listening socket with the IPV6_RECVPKTINFO option enabled.
3) Errors within the implementation of the External Data Representation (XDR) for NFSv4 can be exploited to cause a kernel crash by sending specially crafted compound requests to the NFSv4 server.
