Descriptions
Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel before 4.5.2 allows remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing.
Vulnerabilidad de uso después de liberación de memoria en la función the __sys_recvmmsg en net/socket.c en el kernel de Linux en versiones anteriores a 4.5.2 permite a atacantes remotos ejecutar código arbitrario a través de vectores que involucran una llamada al sistema recvmmsg que no es manejada correctamente durante el procesamiento del error.
A use-after-free vulnerability was found in the kernel's socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.
