CVE-2016-4485

La función llc_cmsg_rcv en net/llc/af_llc.c en el kernel de Linux en versiones anteriores a 4.5.5 no inicializa una estructura de datos determinada, lo que permite a atacantes obtener información sensible del kernel de memoria de pila leyendo un mensaje.

Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the Linux kernel incorrectly enables scatter/gather I/O. A remote attacker could use this to obtain potentially sensitive information from kernel memory. Jann Horn discovered that eCryptfs improperly attempted to use the mmap() handler of a lower filesystem that did not implement one, causing a recursive page fault to occur. A local unprivileged attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. Various other issues were also addressed.
