The robust futex implementation in the Linux kernel before 2.6.28 does not properly handle processes that make exec system calls, which allows local users to cause a denial of service or possibly gain privileges by writing to a memory location in a child process.

Red Hat Security Advisory 2012-0358-01
Posted Mar 6, 2012

Red Hat Security Advisory 2012-0358-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting.

Red Hat Security Advisory 2012-0107-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Using the SG_IO ioctl to issue SCSI requests to partitions or LVM volumes resulted in the requests being passed to the underlying block device. If a privileged user only had access to a single partition or LVM volume, they could use this flaw to bypass those restrictions and gain read and write access to the entire block device. Refer to Red Hat Knowledgebase article DOC-67874, linked to in the References, for further details about this issue.
