kernel: ASLR bypass for setuid binaries due to late install_exec_creds()

A flaw in the loadelfbinary function in the Linux kernel allows a local attacker to leak the base address of .text and stack sections for setuid binaries and bypass ASLR because installexeccreds is called too late in this function...

CVE-2019-11190

The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs such as /bin/su because installexeccreds is called too late in loadelfbinary in fs/binfmtelf.c, and thus the ptracemayaccess check has a race condition when reading /proc/pid/stat...
