CVE-2019-11190: Linux Kernel

Medium severity, CVSS 4.7. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: before 4.8 (fixed in 4.8)
