CVE-2011-1023 is a vulnerability of currently unknown severity. The Reliable Datagram Sockets (RDS) subsystem in the Linux kernel before 2.6.38 does not properly handle congestion map updates, which allows local users to cause a denial of service (BUG_ON and system crash) via vectors involving (1) a loopback (aka loop) transmit operation or (2) an InfiniBand (aka ib) transmit operation.. EPSS estimates a 0.48% chance of exploitation in the next 30 days.
