The virtio_net_bad_features function in hw/virtio-net.c in the virtio-net driver in the Linux kernel prior to 2.6.26, when used on a guest OS in conjunction with qemu-kvm 0.11.0 or KVM 83, allows remote malicious users to cause a denial of service (guest OS crash, and an associat...

The chrp_show_cpuinfo function (chrp/setup.c) in Linux kernel 2.4.21 up to and including 2.6.18-53, when running on PowerPC, might allow local users to cause a denial of service (crash) via unknown vectors that cause the of_get_property function to fail, which triggers a NULL poi...

mm/shmem.c in the Linux kernel prior to 2.6.28-rc8, when strict overcommit is enabled and CONFIG_SECURITY is disabled, does not properly handle the export of shmemfs objects by knfsd, which allows malicious users to cause a denial of service (NULL pointer dereference and knfsd cr...

The parisc_show_stack function in arch/parisc/kernel/traps.c in the Linux kernel prior to 2.6.28-rc7 on PA-RISC allows local users to cause a denial of service (system crash) via vectors associated with an attempt to unwind a stack that contains userspace addresses.

The do_sigaltstack function in kernel/signal.c in Linux kernel 2.4 up to and including 2.4.37 and 2.6 prior to 2.6.31-rc5, when running on 64-bit systems, does not clear certain padding bytes from a structure, which allows local users to obtain sensitive information from the kern...

1 EDB exploit

The do_mremap function for the mremap system call in Linux 2.2 to 2.2.25, 2.4 to 2.4.24, and 2.6 to 2.6.2, does not properly check the return value from the do_munmap function when the maximum number of VMA descriptors is exceeded, which allows local users to gain root privileges...

2 EDB exploits

The eHCA driver in Linux kernel 2.6 prior to 2.6.22, when running on PowerPC, does not properly map userspace resources, which allows local users to read portions of physical address space.

Linux Linux Kernel

Improper access control in BlueZ may allow an unauthenticated user to potentially enable information disclosure via adjacent access.

Linux Linux Kernel

A regression error in the restore_all code path of the 4/4GB split support for non-hugemem Linux kernels on Red Hat Linux Desktop and Enterprise Linux 4 allows local users to cause a denial of service (panic) via unspecified vectors.

Linux Linux Kernel -

arch/arm/mm/dma-mapping.c in the Linux kernel prior to 3.13 on ARM platforms, as used in Android prior to 2016-08-05 on Nexus 5 and 7 (2013) devices, does not prevent executable DMA mappings, which might allow local users to gain privileges via a crafted application, aka Android ...
