Computer memory and processes are critical components of a computer system, and they are often targeted by malware for exploitation. Here are some of the vulnerabilities that malware can take advantage of:

1. Buffer Overflow: This is a common vulnerability where a program writes more data to a buffer than it can handle, causing it to overflow into adjacent memory. Malware can exploit this to execute arbitrary code or cause a system crash.

2. Uninitialized Memory: If a program fails to initialize a memory location before using it, malware can exploit this to read sensitive data or inject malicious code.

3. Memory Leaks: When a program fails to release memory it has allocated, it can lead to a memory leak. Over time, this can consume all available memory, causing the system to slow down or crash. Malware can exploit this to cause a denial of service.

4. Race Conditions: This occurs when the timing or ordering of events affects a program's operation. Malware can exploit this to manipulate data or execute code.

5. Insecure Process Communication: If processes communicate over insecure channels, malware can intercept and manipulate the data.

6. Privilege Escalation: If a process runs with higher privileges than necessary, malware can exploit this to gain unauthorized access or control over the system.

7. Injection Attacks: Malware can inject malicious code into a running process, altering its behavior or allowing the malware to execute its own code.

8. Side-channel Attacks: By observing the timing, power consumption, or other physical characteristics of a system, malware can infer sensitive information about the data being processed.

9. Direct Memory Access (DMA) Attacks: Some hardware devices can read and write memory directly, bypassing the CPU and OS protections. Malware can exploit this to read sensitive data or inject malicious code.

10. Return Oriented Programming (ROP): This is a technique where an attacker uses bits of benign code, called "gadgets", in a way that was not originally intended to bypass security measures and execute malicious code.

To protect against these and other vulnerabilities, it's important to keep software and operating systems up to date, use security software, and follow best practices for secure coding and system configuration.
