CVE-2016-6480

Condición de carrera en la función ioctl_send_fib en drivers/scsi/aacraid/commctrl.c en el kernel de Linux hasta la versión 4.7 permite a usuarios locales provocar una denegación de servicio (acceso fuera de rango o caída de sistema) cambiando un cierto valor de tamaño, también conocido como una vulnerabilidad de "doble recuperación".

A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value.

Philip Pettersson discovered a race condition in the af_packet implementation in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service (system crash) or run arbitrary code with administrative privileges. Pengfei Wang discovered a race condition in the Adaptec AAC RAID controller driver in the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system crash). Marco Grassi discovered a use-after-free condition could occur in the TCP retransmit queue handling code in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
