Description
The vulnerability allows a local attacker to bypass security restrictions on the target system.
The weakness exists in the arch_pick_mmap_layout function in arch/x86/mm/mmap.c due to improper randomizing of the legacy base address. A local attacker can disable stack-consumption resource limits, defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag and bypass the ASLR protection mechanism for a setuid or setgid program.
