The issue concerns the ARM image loading functionality, which fails to properly validate kernel length. This allows local users to potentially read system memory or cause a denial of service by crafting a 32-bit ARM guest kernel in an image, leading to a buffer overflow.

A buffer overflow issue allows local users to read system memory or cause a denial of service via a crafted 32-bit guest kernel. This is related to the process of searching for an appended DTB.

The issue is related to a problem with alignment checking in Xen, which can be exploited by local users to cause a denial of service (crash) by manipulating an unspecified field in a DTB header in a 32-bit guest kernel.

The issue allows local users to read system memory or cause a denial of service via a crafted kernel, triggering a buffer overflow, due to improper validation of the load address for 64-bit ARM guest kernels.

The issue is related to the vgic distr mmio write function in the virtual guest interrupt controller (GIC) distributor. It allows local guest users to cause a denial of service, resulting in a NULL pointer dereference and host crash, when running on an ARM system.

The issue is related to improper restriction of access to hardware features on ARM systems, which can be exploited by local guest users to cause a denial of service, resulting in a host or guest crash. This is related to cache control, coprocessors, debug registers, and other unspecified registers.
