Descriptions

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.

La función net_diag_bc_audit en net/ipv4/inet_diag.c en el Kernel de Linux anterior a v2.6.39.3 no audita adecuadamente bytecode INET_DIAG, lo que permite a usuarios locales provocar una denegación de servicio a través de instrucciones manipuladas INET_DIAG_REQ_BYTECODE en un mensaje netlink, como se demostró por una instrucción INET_DIAG_BC_JMP con un valor zero yes, una vulnerabilidad diferente que CVE-2010-3880.
