CVE-2019-11190 (GCVE-0-2019-11190)

Vulnerability from cvelistv5 – Published: 2019-04-11 23:06 – Updated: 2024-08-04 22:48
VLAI?
Summary
The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs (such as /bin/su) because install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat.
Severity ?
No CVSS data available.
