Descriptions
The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state.
La función dccp_disconnect en net/dccp/proto.c en el kernel de Linux hasta la versión 4.14.3 permite que usuarios locales obtengan privilegios o provoquen una denegación de servicio (uso de memoria previamente liberada) mediante una llamada del sistema de conexión AF_UNSPEC durante el estado DCCP_LISTEN.
A use-after-free vulnerability was found in DCCP socket code affecting the Linux kernel since 2.6.16. This vulnerability could allow an attacker to their escalate privileges.
It was discovered that an out-of-bounds write vulnerability existed in the Flash-Friendly File System in the Linux kernel. An attacker could construct a malicious file system that, when mounted, could cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
