Description

The Linux kernel contains a flaw that may allow a local denial of service. The issue is triggered because the code in binfmt_elf.c fails to properly validate the entry address of ELF executables. With a crafted ELF binary, the kernel can be forced to enter an inifite loop, which will result in loss of availability for the platform. Note that the issue is only present on non-AMD x86_64 systems.
