Descriptions

The sfc (aka Solarflare Solarstorm) driver in the Linux kernel before 3.2.30 allows remote attackers to cause a denial of service (DMA descriptor consumption and network-controller outage) via crafted TCP packets that trigger a small MSS value.

El controlador sfc (también conocido como Solarflare Solarstorm) en el Kernel de Linux anteriores a v3.2.30 permite a atacantes remotos provocar una denegación de servicio (consumo de descriptor de DMA y fallo del controlador de red) a través de paquetes TCP manipulados que provocan valores MSS pequeños.

A flaw was found in how the Linux kernel passed the replacement session keyring to a child process. An unprivileged local user could exploit this flaw to cause a denial of service (panic). Ben Hutchings reported a flaw in the Linux kernel with some network drivers that support TSO (TCP segment offload). A local or peer user could exploit this flaw to to cause a denial of service. Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel implementation of RDS sockets. A local unprivileged user could potentially use this flaw to read privileged information from the kernel. Various other issues were also addressed.
