647416: CVE-2010-3865 kernel: iovec integer overflow in net/rds/rdma.c

The MITRE CVE dictionary describes this issue as:

Integer overflow in the rds_rdma_pages function in net/rds/rdma.c in the Linux kernel allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a crafted iovec struct in a Reliable Datagram Sockets (RDS) request, which triggers a buffer overflow.

Find out more about CVE-2010-3865 from the MITRE CVE dictionary dictionary and NIST NVD.


The Linux kernel as shipped with Red Hat Enterprise Linux 3, 4 and Red Hat
Enterprise MRG did not include support for the RDS Protocol, and therefore are
not affected by this issue. Future kernel updates in Red Hat Enterprise Linux 5
may address this flaw.
