CVE-2017-1000253: Linux Kernel PIE Stack Buffer Corruption Vulnerability
CVE-2017-1000253 · Severity: critical · CVSS 7.8 · Exploited in the wild · Published 2024-09-09
The Linux kernel load_elf_binary() function fails to allocate sufficient space for PIE binaries when CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE is enabled. This results in subsequent PT_LOAD segments being mapped into the memory gap reserved for the stack, leading to memory corruption and potential local privilege escalation.
