CVE-2010-3880

Published: 10 December 2010

net/ipv4/inet_diag.c in the Linux kernel before 2.6.37-rc2 does not properly audit INET_DIAG bytecode, which allows local users to cause a denial of service (kernel infinite loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink message that contains multiple attribute elements, as demonstrated by INET_DIAG_BC_JMP instructions.

From the Ubuntu security team

Nelson Elhage discovered that the Linux kernel IPv4 implementation did not properly audit certain bytecodes in netlink messages. A local attacker could exploit this to cause the kernel to hang, leading to a denial of service.
