Last modified

CVE-2014-5148 is a vulnerability of currently unknown severity. Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to cause a denial of service (crash) and possibly gain privileges via a crafted process.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
