CVE-2010-0307 EXPLOIT
4.7
MEDIUM · CVSS 2.0 · EPSS 0.8% (pctl 56)
Patch early
A public exploit exists.
Description
The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function.
