Descriptions
An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.
Se ha encontrado un fallo de filtrado de información en NFS sobre RDMA en el archivo net/sunrpc/xprtrdma/rpc_rdma.c en el Kernel de Linux. Este fallo permite a un atacante privilegiado de usuario normales filtrar información del kernel
It was discovered that the SUNRPC RDMA protocol implementation in the Linux kernel did not properly calculate the header size of a RPC message payload. A local attacker could use this to expose sensitive information. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.
