Memory-address leakage is a vulnerability that exposes pointers or addresses showing where code or data resides in a process’s memory. These values are usually not secrets on their own, but they can reveal the process’s layout and weaken protections such as address space layout randomization (ASLR), which relies on making memory locations difficult to predict.
In an attack, leaked addresses can help an attacker make later exploitation steps more reliable, such as redirecting program execution or chaining the disclosure with a separate flaw. In applications handling sensitive data, an exploit chain may also put secrets at risk. Defenders should investigate unintended pointer disclosure, keep software and runtimes patched, and avoid treating a small memory leak as harmless when it can be combined with other vulnerabilities.
