CVE-2011-1019

La función dev_load en net/core/dev.c en el kernel de Linux anterior a v2.6.38 permite a usuarios locales eludir las capacidades CAP_SYS_MODULE requeridas y cargar modulos arbitrarios mediante el aprovechamiento de la capacidad CAP_NET_ADMIN.

Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. On non-x86 systems, a local attacker could exploit this to read kernel heap memory, leading to a loss of privacy. Dan Rosenburg discovered that the CAN subsystem leaked kernel addresses into the /proc filesystem. A local attacker could use this to increase the chances of a successful memory corruption exploit. Kees Cook discovered that the IOWarrior USB device driver did not correctly check certain size fields. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges. Various other issues were also addressed.
