Hi all, Commit d6c763afab14 "arm64/mm: Remove hack in mmap randomize layout" fixes a security issue which reduces the entropy for mmap base address by half [1]. A attempt to guess where the stack is mapped via brute-force needs just half the attempts. I found this patch was added to v3.19-rc1 but should be added as well to: v3.18, v3.14, v3.12 and v3.10 Best regards, Matthias Brugger [1] http://hmarco.org/bugs/linux-ASLR-reducing-mmap-by-half.html -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
