ASLR Disabled Via Sysctl or Direct Syscall - Linux
Detects actions that disable Address Space Layout Randomization (ASLR) in Linux, including: - Use of the `personality` syscall with the ADDR_NO_RANDOMIZE flag (0x0040000) - Modification of the /proc/sys/kernel/randomize_va_space file - Execution of the `sysctl` command to set `kernel.randomize_va_space=0` Disabling ASLR is often used by attackers during exploit development or to bypass memory protection mechanisms. A successful use of these methods can reduce the effectiveness of ASLR and make memory corruption attacks more reliable.
