Descriptions

The rd_build_device_space function in drivers/target/target_core_rd.c in the Linux kernel before 3.14 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from ramdisk_mcp memory by leveraging access to a SCSI initiator.

La función rd_build_device_space en drivers/target/target_core_rd.c en el kernel de Linux anterior a 3.14 no inicializa debidamente cierta estructura de datos, lo que permite a usuarios locales obtener información sensible de la memoria ramdisk_mcp mediante el aprovechamiento del acceso a un iniciador SCSI.

An information leak flaw was found in the RAM Disks Memory Copy (rd_mcp) backend driver of the iSCSI Target subsystem of the Linux kernel. A privileged user could use this flaw to leak the contents of kernel memory to an iSCSI initiator remote client.

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.
