net/dcb/dcbnl.c in the Linux kernel prior to 3.8.4 does not initialize certain structures, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.

Linux Linux Kernel 3.8.2 Linux Linux Kernel 3.8.0 Linux Linux Kernel Linux Linux Kernel 3.8.1

The rtnl_fill_ifinfo function in net/core/rtnetlink.c in the Linux kernel prior to 3.8.4 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.

Linux Linux Kernel 3.8.2 Linux Linux Kernel 3.8.0 Linux Linux Kernel Linux Linux Kernel 3.8.1

The flush_signal_handlers function in kernel/signal.c in the Linux kernel prior to 3.8.4 preserves the value of the sa_restorer field across an exec operation, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application containing a sig...

Linux Linux Kernel 3.8.2 Linux Linux Kernel 3.8.0 Linux Linux Kernel Linux Linux Kernel 3.8.1

Use-after-free vulnerability in arch/x86/kvm/x86.c in the Linux kernel up to and including 3.8.4 allows guest OS users to cause a denial of service (host OS memory corruption) or possibly have unspecified other impact via a crafted application that triggers use of a guest physica...

Linux Linux Kernel 3.8.2 Linux Linux Kernel 3.8.0 Linux Linux Kernel Linux Linux Kernel 3.8.1 Linux Linux Kernel 3.8.3

The kvm_set_msr_common function in arch/x86/kvm/x86.c in the Linux kernel up to and including 3.8.4 does not ensure a required time_page alignment during an MSR_KVM_SYSTEM_TIME operation, which allows guest OS users to cause a denial of service (buffer overflow and host OS memory...

Linux Linux Kernel 3.8.2 Linux Linux Kernel 3.8.0 Linux Linux Kernel Linux Linux Kernel 3.8.1 Linux Linux Kernel 3.8.3

The ioapic_read_indirect function in virt/kvm/ioapic.c in the Linux kernel up to and including 3.8.4 does not properly handle a certain combination of invalid IOAPIC_REG_SELECT and IOAPIC_REG_WINDOW operations, which allows guest OS users to obtain sensitive information from host...

Linux Linux Kernel 3.8.2 Linux Linux Kernel 3.8.0 Linux Linux Kernel Linux Linux Kernel 3.8.1 Linux Linux Kernel 3.8.3

The create_user_ns function in kernel/user_namespace.c in the Linux kernel prior to 3.8.6 does not check whether a chroot directory exists that differs from the namespace root directory, which allows local users to bypass intended filesystem restrictions via a crafted clone syste...

Linux Linux Kernel 3.8.2 Linux Linux Kernel 3.8.0 Linux Linux Kernel Linux Linux Kernel 3.8.1 Linux Linux Kernel 3.8.3 Linux Linux Kernel 3.8.4

The clone_mnt function in fs/namespace.c in the Linux kernel prior to 3.8.6 does not properly restrict changes to the MNT_READONLY flag, which allows local users to bypass an intended read-only property of a filesystem by leveraging a separate mount namespace.
