Descriptions
The ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel before 2.6.37 does not initialize a certain response buffer, which allows local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially filled, a different vulnerability than CVE-2010-4649.
La función ib_uverbs_poll_cq en drivers/InfiniBand/core/uverbs_cmd.c en el kernel de Linux antes de v2.6.37 no inicializa determinado buffer de respuesta, lo que permite obtener información sensible de la memoria del kernel a usuarios locales a través de vectores que causan que este búfer este sólo parcialmente lleno. Se trata de una vulnerabilidad diferente a CVE-2010-4.649.
