CVE-2011-2213

Priority
Description
The inet_diag_bc_audit function in net/ipv4/inet_diag.c in the Linux kernel
before 2.6.39.3 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, as demonstrated
by an INET_DIAG_BC_JMP instruction with a zero yes value, a different
vulnerability than CVE-2010-3880.
Ubuntu-Description
Dan Rosenberg discovered that the IPv4 diagnostic routines did not
correctly validate certain requests. A local attacker could exploit this to
consume CPU resources, leading to a denial of service.
